Dynatrace pro certification study set exam test with complete solution

Dynatrace pro certification study set exam test with complete solution Dynatrace ActiveGate - Correct Answer Dynatrace ActiveGate serves as a proxy between Dynatrace OneAgent and Dynatrace Server. ActiveGate is highly recommended for both SaaS and Managed deployments." "Dynatrace Managed (Managed deployments only) - Correct Answer If you're setting up a Dynatrace Managed deployment, your first step is to obtain a Dynatrace Managed license. Following that, you can install Dynatrace Managed. Dynatrace SaaS customers should skip this step and begin by installing ActiveGate." "Dynatrace OneAgent - Correct Answer Dynatrace OneAgent is responsible for collecting all monitoring data within your monitored environment." "Mission Control security - Correct Answer All communication with Mission Control is secure and performed via HTTPS with browser-like certificate checks. All Dynatrace Managed configuration changes are fully audit-logged and each remote access is logged as a separate event (click the Events tile on your Dynatrace Managed home page to view the list of recorded events). The Mission Control team can't access certificates or user credentials. They also can't gain root access to any servers." "How are new problems evaluated and raised? - Correct Answer Dynatrace continuously measures incoming traffic levels against defined thresholds to determine when a detected slowdown or error-rate increase justifies the generation of a new problem event. Rapidly increasing response-time degradations for applications and services are evaluated based on sliding 5-minute time intervals. Slowly degrading response-time degradations are evaluated based on 15-minute time intervals." "Don't have access to your application's web server? Consider these other deployment options - Correct Answer If you don't have access to your web server and can't install OneAgent you can set up agentless monitoring. If setting up agentless monitoring isn't feasible in your environment, try the RUM browser extension. For applications that can't be monitored by OneAgent, like traditional rich-client applications, digital service terminals (for example, ATMs), or smart IoT applications, use Dynatrace OpenKit." "How does Mission Control pro-active support work? - Correct Answer Dynatrace Managed automatically solves many common maintenance and support challenges for you. With Dynatrace Mission Control, you get fully automated management capabilities in a pro-active way that keep Dynatrace Server secure, reliable, and up-to-date—all while saving you from the hassles of administrative tasks like upgrades and troubleshooting. Once you've granted the required permissions, our Mission Control team can remotely access your Dynatrace Server to assist with upgrades and troubleshooting when you run into problems." "How Mission Control works - Correct Answer To facilitate pro-active support, your Dynatrace Server transmits status information to and from Dynatrace Mission Control. The only data that our Mission Control team can access comes from the server component of your Dynatrace Managed installation. At no time can our Mission Control team access your operating system or file system. Our goal is to provide the highest possible system uptime (> 98%) and processing rate (> 99.5%) for collected monitoring data." "What Mission Control does - Correct Answer Dynatrace Mission Control is responsible for sending Usage and billing information Dynatrace Server health statistics Once permission is granted, our Mission Control team can remotely analyze the hardware utilization of your Dynatrace Managed installation and alert you if more resources are required. Dynatrace Server event tracking Events like server starts/shutdowns, added/removed nodes, and ActiveGate registrations are tracked automatically. Our Mission Control team can remotely analyze and address problems or incompatibilities with your Dynatrace Server, so you don't need to track and react to system events. If you should ever need to contact Dynatrace Support, you won't need to collect the required log files for problem details—Mission Control gathers this data for your automatically. To see the list of Dynatrace Server system events that are automatically logged, click the Events tile on your Dynatrace Managed home page. System settings Our Mission Control team can remotely optimize your Dynatrace Managed settings to ensure optimum performance and stability. Software updates Dynatrace Managed software updates are mandatory and are typically published every four weeks. You can customize the timing of Dynatrace Managed updates (daily or weekly). Updates are automatically communicated to your users at least 24 hours in advance. Dynatrace Managed updates are fast and allow monitoring to continue seamlessly." "Note that newly detected anomolous events in your environment..... - Correct Answer ....won't necessarily result in the immediate raising of a new problem. Raised problems always provide insight into the underlying root cause. To identify the root causes of problems, Dynatrace analyzes the correlation of events across time, processes, hosts, services, applications, and both vertical and horizontal topological monitoring perspectives. Only by correlating events across time and all these monitoring perspectives can Dynatrace pinpoint the root causes of problems. And only then will you be alerted to a detected problem. For more details, see automatic correlation of dependent toplological incicents." "Understanding thresholds Dynatrace utilizes three types of thresholds: - Correct Answer Automated baselines: Multidimensional baselining automatically detects individual reference values that adapt over time. Automated baseline reference values are used to cope with dynamic changes within your application or service response times, error rates, and load. Built-in static thresholds: Dynatrace uses built-in static thresholds for all infrastructure events (for example, detecting high CPU, low disk space, or low memory). User-defined static thresholds: With customizable anomaly detection settings (available at Settings > Anomaly detection), you can overwrite the default static thresholds for infrastructure events. You can also switch from automated baselining for application and service anomaly detection to static thresholds. With static thresholds, the detected baseline thresholds are overwritten by your custom static thresholds for individual dimensions." "What is a monitoring environment? - Correct Answer Your Dynatrace monitoring environment is where all your Dynatrace performance analysis takes place. Dynatrace OneAgent sends all captured monitoring data to your monitoring environment for analysis. A monitoring environment is analogous to an analysis server that provides all Dynatrace application-performance analysis functionality, including all dashboards, charts, reports and other tools." "What is a monitoring environment? - Correct Answer Your monitoring environment resides in the Dynatrace cloud, unless you're using our on-premises deployment option, Dynatrace Managed. For Dynatrace Managed customers, your monitoring environment is hosted within your own data center." "Multiple monitoring environments - Correct Answer It's common to set up multiple monitoring environments so that related entities can be grouped for discrete analysis. For example, you might set up one monitoring environment to monitor and analyze the performance of your production clusters. You might set up a second environment that's dedicated to the performance of your developers' machines and a third environment for your staging servers. How you segment your monitoring environments is entirely up to you. For details on how to set up multiple monitoring environments, please check Can I set up multiple monitoring environments? if you've chosen the SaaS option or How can I create and manage my monitoring environments? for Dynatrace Managed." "Get started with Dynatrace SaaS - Correct Answer Step 1: Create your Dynatrace account Step 2: Install OneAgent and Environment ActiveGate Step 3: Fine tune your environment" "Step 1: Create your Dynatrace account - Correct Answer The first thing you need to do is create a Dynatrace account. To do this, visit the Dynatrace web site and click the Free trial button. You'll be prompted to provide an email address, password, contact information, and your region. You'll then arrive at the page shown below. If you click Deploy Dynatrace, you can start installation. However, prior to installation, you have the option of viewing some sample monitoring data to get a preview of Dynatrace before you install OneAgent. To see the basic Dynatrace dashboard, navigation menu, and tiles, click the View example data link (see image above). You can then click any of the example dashboard tiles (tagged with Example labels) to get a preview of how Dynatrace works. With the completion of this step, you have essentially created your monitoring environment on the Dynatrace cluster. Your monitoring environment is identified via a unique environment id, that you can see at the beginning of your Dynatrace SaaS URL." "Step 2: Install OneAgent and Environment ActiveGate - Correct Answer If your network allows SSL communication with the Dynatrace cluster, you're ready to install OneAgent. Otherwise, before installing OneAgent, you need to install an Environment ActiveGate. Environment ActiveGate works as a proxy between Dynatrace OneAgent and Dynatrace cluster. Even if your network allows SSL communication with Dynatrace cluster, you still need to install ActiveGate for specific use cases, for example if you want to monitor a large number of hosts. Note: If you don't have access to your web server and can't install OneAgent, you can set up any of the following: Synthetic monitoring. Agentless monitoring. RUM browser extension. For applications that can't be monitored by OneAgent, such as traditional rich-client applications, digital service terminals (for example, ATMs), or smart IoT applications, use Dynatrace OpenKit." "Step 3: Fine tune your environment - Correct Answer You can now access your home dashboard, by logging in to your Dynatrace monitoring environment. All monitoring data should be there already. However, some additional post-deployment steps are required. Define your applications landscape using My web application. Activate the suitable JavaScript framework to get additional monitoring data. Make sure that the auto-detected processes meet your expectations and fit your needs. If this is not the case, you can adapt the composition and/or naming of the default process groups. Customize your dashboard according to your preferences and needs. You can create separate dashboards for your most important applications or you can create a dashboard showing the health for your most critical infrastructure components. Set up the required notifications. In case you want to modify the conditions under which you want to be notified, you can also set up customized alerting rules. Define management zones to filter all Dynatrace views so that your organization's teams only see the metrics that are related to the entities that they are responsible for monitoring." "Get started with Dynatrace Managed - Correct Answer For customers who don't want to expose their infrastructure to the internet, we offer an on-premises deployment model of Dynatrace called Dynatrace Managed. With Dynatrace Managed, you get automated support from our Mission Control team. You can read about Mission Control and service quality, as well as bilateral contractual obligations, in the Dynatrace Managed Mission Control and Service Level Agreement." "Step 1: Obtain a Dynatrace Managed license - Correct Answer To obtain a license for Dynatrace Managed, contact Dynatrace Sales. Your Sales rep will provide you with further details regarding Dynatrace Managed. Once an agreement is reached, you'll receive an email that includes your license details as well as instructions on how to set up your Dynatrace Managed Cluster." "Step 2: Set up your Managed cluster - Correct Answer To properly set up your Managed cluster, you should first identify the deployment model that best suits your needs. Subsequently, you can install Dynatrace Managed to create your first cluster node. You can add more nodes at any time." "Step 3: Install OneAgent and ActiveGate - Correct Answer To monitor your environments, install OneAgent on each environment. You can also install Environment ActiveGates and Cluster ActiveGates as required, based on the deployment model you've selected." "Step 4: Fine tune your environment - Correct Answer You can now access your home dashboard, by logging in to your Dynatrace monitoring environment. All monitoring data should be there already. However, some additional post-deployment steps are required. Define your applications landscape using My web application. Activate the suitable JavaScript framework to get additional monitoring data. Make sure that the auto-detected processes meet your expectations and fit your needs. If this is not the case, you can adapt the composition and/or naming of the default process groups. Customize your dashboard according to your preferences and needs. You can create separate dashboards for your most important applications or you can create a dashboard showing the health for your most critical infrastructure components. Set up the required notifications. In case you want to modify the conditions under which you want to be notified, you can also set up customized alerting rules. Define management zones to filter all Dynatrace views so that your organization's teams only see the metrics that are related to the entities that they are responsible for monitoring." "Dynatrace OneAgent - Correct Answer OneAgent is responsible for collecting all monitoring data within your monitored environment. A single OneAgent per host is required to collect all relevant monitoring data—even if your hosts are deployed within Docker containers, microservices architectures, or cloud-based infrastructure." "Dynatrace OneAgent - Correct Answer A single instance of OneAgent can handle monitoring for all types of entities, including servers, applications, services, databases, and more. OneAgent gives you all the operational and business performance metrics you need, from the front-end to the back-end and everything in between—cloud instances, hosts, network health, processes, and services. OneAgent discovers all the processes you have running on your hosts. Based on what it finds, OneAgent automatically activates instrumentation specifically for your unique application stack. It also injects all tags required for user-experience monitoring into the HTML of your application pages. New components are auto-instrumented on the fly. OneAgent is comprised of several code modules that enable OneAgent to work for most technologies out-of-the-box. To find out which code modules are supported for each platform, see the OneAgent platform and capability support matrix. To see which versions are supported for each code module, see OneAgent supported technologies and versions. For more information on support models for various technologies, see Supported languages and frameworks below." "4 things you'll absolutely love about Dynatrace - Correct Answer Smartscape, Problem evolution player, Dynatrace home dashboard and tiles, and Search for components in your environment by name" "Smartscape - Correct Answer Smartscape auto-discovers and shows you your complete environment. It provides a real-time view of all the components and processes in your application infrastructure—so it's ideal for monitoring the success of rapid deployments. Out of the box Smartscape shows you: Cross-tier and same-tier process, service, and application dependencies Performance of dependencies and their impact on application performance Third-party dependencies and their impact on performance Host communication Quick access to detail drill-downs" "Problem evolution player - Correct Answer We like to think of problems as stories. A chain of events with a beginning, turning points, culmination, and closure. We can tell you these stories with our Problem Evolution player. It combines and presents all events that contribute to application performance degradation. Instead of sending you individual alert messages for each insignificant or unrelated event, we show you the whole story. You can investigate each issue from the point where it started, through root-case analysis, and all the way to its ultimate resolution." "Dynatrace home dashboard and tiles - Correct Answer We've designed the home dashboard so that you can see everything that's going on in your monitored environment at a single glance. The home dashboard contains tiles which show you important measurements in real-time and inform you of any conditions that require your attention. You can use the tiles as entry points for deeper analysis of your application health or user satisfaction of your website. On the home dashboard you can: Instantly see problem notifications and the source of problems. See crucial measurement values so that you can quickly assess issues. Customize your view (Yes, you can add more tiles!) Customize what's displayed on individual tiles. Group tiles into meaningful sections." "Search for components in your environment by name! - Correct Answer Our search box may be compact in size, but the gears behind it give you the power to quickly isolate any component in your application environment. With Dynatrace super search, you can search for virtual and physical hosts, applications, services, processes, and other entities by name! That's not all—you also get a list of all related discussion threads in our Answers forum and links to all related Dynatrace Help topics and blog posts." "What is an access token? - Correct Answer Dynatrace relies on unique character strings to identify your monitoring environment. This is necessary to enable, for example, external integration of your Dynatrace monitoring environment with 3rd party messaging services, Dynatrace REST API, PaaS environments, VoiceOps/ChatOps, and other reporting tools. All external access to your Dynatrace monitoring environment relies on two major pieces of information: the environment ID and an access token. Authentication required for Dynatrace OneAgent downloads or for accessing the Dynatrace API is achieved using access keys called tokens. Dynatrace defines the scope of tokens to limit access to specific product functionality for security reasons. A PaaS token, for example, allows the download of OneAgent for PaaS and installation of OneAgent on multiple hosts, but it doesn't enable you to access the rest of the Dynatrace API. There are some situations where required tokens are automatically created and other situations where they must be generated manually. For example, OneAgent for Windows ships with a token automatically. Conversely, OneAgent for PaaS requires that you manually generate an access token." "Create user-generated access tokens - Correct Answer To generate and manage access tokens Log into your Dynatrace environment and from the navigation menu click Settings > Integration. Select Dynatrace API, Platform as a Service, or Dynatrace modules to generate a token for the Dynatrace API, a token for PaaS, or a token for DCRUM or Synthetic. Click the Generate token button, then type a meaningful token name in the text field. Note: The uniqueness of user-generated token names is not checked. Multiple same-named API, PaaS, or module tokens can exist. Be sure to provide a meaningful name for each token you define. Multiple same-named tokens can have different access configurations. Effective token naming helps you to efficiently manage your tokens, search for tokens, and perhaps delete them in the future if they're no longer needed. (Optional) For creating Dynatrace API tokens, select or clear access switches as needed to set the access scope of the API token. For example, to create an API authentication token to access Dynatrace monitoring data for user session queries, select User session query language. Click the Generate button. The token appears in the My Dynatrace token list below. A t any time, you can copy an access token that you created by expanding Edit next to the token name and clicking the Copy button next to the token. Token management view also allows you to Disable/enable, Edit, or Delete tokens." "Locate existing access tokens - Correct Answer As is the case with environment IDs (see above), access tokens also appear in URLs, though at the end of URLs rather than at the beginning. For example, note the access token at the end of URL that appears in the Use this command on the target host text field in the image below." "Why do I need an environment ID? - Correct Answer Dynatrace relies on unique character strings to identify your monitoring environment. This is necessary to enable, for example, external integration of your Dynatrace monitoring environment with 3rd party messaging services, Dynatrace REST API, PaaS environments, VoiceOps/ChatOps, and other reporting tools. All external access to your Dynatrace monitoring environment relies on two major pieces of information: the environment ID and an access token. Each environment that you monitor with Dynatrace is identified with a unique character string (i.e., your environment ID). The Dynatrace API relies heavily on environment IDs to ensure that it pulls monitoring data from and pushes relevant external events to the correct Dynatrace environments. Within Dynatrace SaaS, your Dynatrace environment ID (otherwise known as a tenant ID), is included at the beginning of your Dynatrace environment´s URL (see highlight in image below). In case you are operating your own Dynatrace Managed installation, you can find your environment id within your custom domain path after the /e/ subpath (see highlight in image below). You can also find your environment ID listed on your Dynatrace account page along with your licensing details. To find this page, click the User menu button in the upper-right corner of the menu bar and select Account settings." "Environment IDs for PaaS, Linux/AIX/Solaris, & containerized environments - Correct Answer If your environment is PaaS-based, built on Linux/AIX/Solaris, or is containerized, follow these steps to locate your environment ID. Select Deploy Dynatrace from the navigation menu. If you have a PaaS-based infrastructure: Click the Set up PaaS integration button. Your environment ID appears in the Environment ID text box. If your infrastructure is based on Linux/AIX/Solaris: Click Start installation and select your operating system (Linux/AIX/Solaris). Your environment ID appears at the beginning of the URL included in the Use this command on the target host text box. If you have a containerized infrastructure: Click Start installation and select Linux. Your environment ID appears at the beginning of the URL included in the Use this command on the target host text box." "Can I set up multiple monitoring environments? - Correct Answer You may want to set up separate Dynatrace monitoring environments that are dedicated to the monitoring of your organization's development, staging, and production environments. Or possibly you want to maintain a separate monitoring environment for each of your organization's data centers. For these reasons and more, Dynatrace allows you to monitor multiple environments simultaneously with a single Dynatrace account. The data from each additional monitoring environment you create are separated from the monitoring data that are collected from your other environments. It's easy to switch between monitoring views for separate environments to track the performance and availability of each environment. In addition to sharing the same Dynatrace account, each monitoring environment also shares the same user base and other account settings. If you're interested in setting up additional monitoring environments, please contact Dynatrace Sales." "User session - Correct Answer One or more user actions that comprise an interaction between a user's browser and your application. User sessions (aka, "user visits") end when the user's browser closes or is inactive for 30 minutes. Note that bounced sessions (sessions with only a single action) don't count against your licensed session quota. Dynatrace typically shows all the sessions of each individual user, even when those sessions are anonymous (non-authenticated users identified with browser cookies) or when a user tag has been edited or deleted. For mobile apps, Dynatrace identifies individual users based on the specific mobile device they use. For web applications, user identification is achieved by storing a persistent cookie within each user's browser. Cookies enable Dynatrace to assign even anonymous user sessions to known users. As long as a user has logged into your application at least once, you can search for and identify that user, even when the user accesses your application within anonymous, unauthenticated sessions. This is particularly useful for analyzing periods of time when a user may not have been able to log into your application due to an issue with your authentication service." "User action - Correct Answer Actions your customers perform within your application. User actions equate to common user activities such as performing a search, viewing an account balance, viewing items in a shopping cart, or ordering a product. User actions vary based on the features of your application. From the Dynatrace perspective, each user action contains all client activity that occurs during the transition from one state to another. Each user action contains at least one web request because when a user navigates to a page, the browser downloads multiple resources and calls the JavaScript onload handler, which in turn may perform XHR requests and more. The duration of a user action is called action duration. This represents the time that the user must wait before they can proceed. So a low action duration is better than a high action duration. For more details, see What are user actions?." "What are user actions? - Correct Answer A user action is an interaction with the web browser that involves a call to a web server, which can potentially have multiple nested calls. A user action can be a page load, an XHR action or a custom action. The key difference among these action types is the way action duration is calculated and that for each type there are different metrics available." "Page load - Correct Answer A page load is an actual page loading in your browser. If you enter a URL in your browser and press enter, a page load occurs. During a page load, many resources are loaded, including images, HTML, and CSS. The action duration in this case is the time required for the complete page load. More specifically, the start time of the user action begins with the W3C navigationStart time, if available. If not available, the start time begins when the Real User Monitoring JavaScript code is initialized in the browser. The end time is when the last onload handler has completed its task. The onload handler is an event handler in JavaScript that's used to call the execution of JavaScript after a page, frame, or image has completely loaded. If any XMLHttpRequests (see XHR actions below) are started by an onload handler, the user action ends when the XMLHttpRequest is complete." "XHR action - Correct Answer Most modern applications, including single page applications, rely on a single page load that downloads the framework and initializes the page. After that, the DOM of the page is changed via JavaScript and all communication with the web server is done via XmlHttpRequest or via fetch(). Dynatrace continuously tracks user interactions with each page. If user interaction leads to XmlHttpRequests or fetch() calls, an XHR action is created. Dynatrace also detects if there are additional XHRs triggered in the callback of the initial XHR and so on. In this case, Dynatrace waits until all requests are finished. By monitoring the DOM, Dynatrace can also identify resources that were added in the callbacks. Dynatrace then waits until those resources have finished downloading before ending the action." "Fetch API - Correct Answer The Fetch API provides an interface for fetching resources (including across the network). It is similar to XMLHttpRequest, but the API provides a more flexible feature set. The generic definitions of Request, Response and other network request objects in Fetch allow them to be used at any time they are needed, whether it's for service workers, Cache API, or anything that handles or modifies requests and responses. Fetch also supports the Cross Origin Resource Sharing (CORS). User actions based on the Fetch API appear in Dynatrace as XHR actions. You can configure Dynatrace to automatically detect and capture Fetch API request information. To enable Fetch API detection Select Applications from the navigation menu, then select the application you want to configure. On the application page, click the Browse (...) button in the top right corner and choose Edit to access settings for the specified application. Click Async requests and single page apps, then on the Async requests and single page apps page, select the Capture fetch() requests option. You can also use the settings on the Async requests and single page apps page to enable support detection of XmlHttpRequest by selecting Support for XmlHttpRequests. In addition you can enable support for specific JavaScript frameworks by selecting the respective switches in the JavaScript framework support section of the page." "User action naming rules - Correct Answer Many applications allow users to accomplish the same goal through different UI controls. When monitoring such applications, it can be difficult to differentiate between actions that have the same result and goal, but are executed using different parts of the application UI. Likewise, if the UI of an application is translated into multiple languages, the same application function or control may appear under varying names. With user action naming rules, Dynatrace can detect such subtle variations and intelligently group related user actions (i.e., user actions that achieve the same goal) into logical groups for monitoring. Dynatrace automatically removes certain common sessionid tokens from user action names (for example, jsessionid for Java containers, the default sessionid for PHP, and CFID and CFTOKEN for ColdFusion). Nonetheless, there are numerous session ID variations that may be present in your environment. If Dynatrace doesn't automatically recognize and remove session IDs from certain user action names you encounter, you'll need to configure custom naming rules for those user actions." "User action contributors - Correct Answer The duration of a user action can be broken down into three components: Network time: the time required for data transfer Server time: the time consumed on the server side Frontend time: the time required for the browser to render the page So these components contribute to the overall duration of a user action; hence the term "user action contributors". Summing up from the description in the previous sections, a user action duration is calculated as follows: User action duration = (loadEventEnd or endTimeOfLastXHR) - actionStart where: -actionStart: navigationStart for page loads or "click time" for XHR actions and user navigations like a button click or click on a link -endTimeOfLastXHR: if XHR calls are triggered during the process and aren't finished before loadEventEnd then the end time of the last XHR call is used instead of the loadEventEnd time The user action contributors are calculated as follows: Server consumption = responseStart - requestStart Network consumption = (requestStart - actionStart) + (responseEnd - responseStart) Frontend time = direct from the W3C navigation timings" "Custom action - Correct Answer Rather than relying on default user action generation, you may want to fine-tune your Real User Monitoring by adding additional user actions directly into your application's HTML. This can be useful if our automated user-action generation doesn't catch specific actions or you want to introduce specific fine-grained timings into your application monitoring. For example, you could measure how long it takes to open a JavaScript-only drop-down menu, or measure the duration time of some JavaScript code. To define custom actions you can use the JavaScript API for Real User Monitoring." "timeframe selector - Correct Answer The analysis timeframe selection tool that's in the upper-right corner of all Dynatrace pages and views. The timeframe selector enables you to filter monitoring data down to a specific time range. Previous and Next buttons enable you to move forward and backward in time based on pre-defined increments (30 minutes, 1 hour, 1 day, 1 week, etc.). Selected timeframes remain persistent even when you move between pages and views." "Synthetic monitoring - Correct Answer Application availability and performance can be experienced differently by different customers around the world at any given time. Dynatrace Synthetic monitoring makes it easy for you to monitor application availability and performance as your customers experience it, around the world and around the clock. Synthetic monitoring proactively simulates user visits even when no users are currently visiting your site. Synthetic monitoring provides 24x7 global visibility into your web applications by driving real web browser sessions with full HTML5/Ajax support." "Synthetic action - Correct Answer The equivalent of a simulated user action. When a Browser clickpath triggers the loading of a new page or an XHR request, Dynatrace monitors the availability and performance of that action." "Smartscape - Correct Answer Using proprietary Smartscape technology, Dynatrace is able to automatically discover your entire application stack, from the data centers, hosts, and processes that comprise your infrastructure and network, through the services that comprise your applications, and extending all the way up to your applications. Dynatrace even discovers and maps all of the dependencies of these components, in real time. Dynatrace then presents its findings to you in an interactive Smartscape topology map. You can click anywhere within a Smartscape visualization to view performance statistics for each discovered entity in your environment." "Service quality report - Correct Answer An easy-to-read report that summarizes the monitoring insights that Dynatrace has compiled over the past week. Service quality reports are structured in such a way that even non-technical team members can understand them. Reports calculate how well your monitored components perform and provides scores for the following areas: Overall environment Applications Services Infrastructure Service quality reports give you insights into hot spots in your environment and make it easy to share insights with others." "Service backtrace - Correct Answer A visualization of all the services that send requests to a specific back-end service. More than just showing which services directly call a specific back-end service, Service backtrace shows you the sequence of service calls that leads up to each request, all the way back up to the browser click that triggered the sequence of calls." "Service - Correct Answer Server-side code executed within a process group." "Server-side service - Correct Answer Web and mobile applications are built upon services that process requests like web requests, web service calls, and messaging. For example, the web requests that are sent to a specific Tomcat server are an example of a server-side service. Such services can take the form of web services, web containers, database requests, custom services, and more. Services may in turn call other services such as web services, remote services, and databases services. Processes are essentially containers that host services. When you look at processes you are looking at topology information, whereas services can provide code-level insights. For example, you might have a Tomcat process that hosts a web application in the form of a server-side service. While processes are host-centric—associated with a single machine in your environment—services are request-centric and therefore typically span across multiple machines in a data center." "Root cause analysis - Correct Answer The Dynatrace AI-driven process for understanding why detected problems occurred, along with guidance for resolving the underlying causes of problems. Dynatrace identifies performance problems before your customers are affected by them and prioritizes problems based on customer impact, providing instant insight into problem severity and user experience impact. When Dynatrace discovers performance problems, it provides you with a single problem notification that identifies the root cause of the problem so you don't have to manually interpret dozens of data sources to figure out what needs to be fixed. Because performance problems are seldom isolated events (they're usually symptoms of larger issues), Dynatrace artificial intelligence can analyze up to billions of events that occur within your IT environment to help you address the causes of problems, not the symptoms. Dynatrace root cause analysis also streamlines bug fixing through deep-dive analysis into source code and database statements, letting you cut down mean time to repair by 90% or more." "Response time - Correct Answer The time it takes for a service to execute and complete a task." "Overall Dynatrace score - Correct Answer Your overall Dynatrace score is an average of the application, services, and infrastructure scores for your environment. For example if your individual scores are Applications: 85, Services: 99, and Infrastructure: 94, then your Dynatrace score is 92 (278/3)." "Application score - Correct Answer Application scores are based on application Apdex ratings. In brief, the Application score is the average of your application Apdex value and the percentage of user actions that are not affected by problems." "Services score - Correct Answer This score represents the percentage of service calls that were successful and unaffected by problems." "Infrastructure score - Correct Answer This score is the percentage of host time during which no problems were encountered." "How often are reports generated? - Correct Answer Service quality reports are generated each week on Sundays at midnight so that when you start your work week each Monday morning you'll find a new report ready for your review. To subscribe to weekly service quality report emails Select Reports from the navigation menu. Click a Service quality report to open the report. Click the Browse (...) button. Click Subscribe. If you're unsure if you've already viewed a report for a given week, select Reports from the navigation menu. Then click the Unread filter to display all unread reports." "How do I share reports? - Correct Answer You can share service quality reports with anyone, including both registered Dynatrace users and non-users. To share a service quality report using email Select Reports from the navigation menu. Click a Service quality report to open the report. Click the Browse (...) button. Click Share to display the sharable link for the report. Click Copy to copy the URL to your clipboard. Paste the sharable URL into an email to the recipient. When you share a report with a non-Dynatrace user, the user receives a message with a private link that allows them to view the report without logging into Dynatrace." "Real user monitoring - Correct Answer Real user monitoring analyzes the experience that your customers have while interacting with your application. Real user monitoring is a combination of web analytics and performance measurements that build a picture of how well your customer-facing components perform." "Process responsiveness - Correct Answer An assessment of process health based on response-time metrics that measure how long it takes to react to requests from other processes or clients (regardless of resource consumption)." "Process group - Correct Answer A set of processes that perform the same function across multiple hosts. For example, you might have a cluster of servers with each server running the same process in support of multiple hosts." "Process - Correct Answer A process is an instance of an executed computer program. Processes serve as containers that host services. When you look at processes you see topology information, whereas services give you code-level insight. For example, you might have a Tomcat process that hosts a web application in the form of a server-side service. While processes are host-centric—associated with a single machine in your environment—services are request-centric and therefore typically span across multiple machines in a data center." "Problem - Correct Answer A logical grouping of information in Dynatrace that includes the AI-driven analysis, environmental context, root cause analysis, and other details provided for one or more incidents in your environment. Problems can express themselves in your environment as performance degradations, improper functionality, or lack of availability. A problem can be the result of a single "event" or multiple events." "Prediction-based anomaly detection - Correct Answer Evaluating traffic and load anomalies carries different assumptions than evaluating performance anomalies. Dynatrace uses a range of measures and methodologies to identify performance anomalies that affect customer experience and therefore require your attention. However, traffic and load anomalies are based on daily, seasonal, and business-cycle related patterns driven by an application's business model, related marketing efforts, and sociological factors. These are fairly predictable cycles that impact traffic and load as customers use your application. Examples of predictable cycles include weekends/workweeks, workday/evening hours, and customer activity occurring on an annual cycle, such as Black Friday. Because of this, Dynatrace uses a prediction-based methodology approach to detect abnormalities in application traffic and service load." "Opaque service - Correct Answer A service detected on the calling side by Dynatrace for which code-level visibility isn't available. Dynatrace can detect requests of opaque services and identify which processes they're processed by, but Dynatrace can't monitor opaque services directly." "oneagentmon driver - Correct Answer A special device that appears in your Windows system during Dynatrace OneAgent installation. It's indispensable for deep monitoring purposes, as it allows Dynatrace OneAgent to add its own library between the system and the monitored processes." "oneagentmon device - Correct Answer "oneagentmon device" appears in your Windows system during Dynatrace OneAgent installation. It's used by Dynatrace for deep process monitoring. It works like a monitoring driver and allows Dynatrace OneAgent to add its own library between the operating system and the processes it's monitoring." "OneAgent for iOS - Correct Answer Dynatrace's mobile app support for iOS, which lets you track user behavior on mobile web pages. OneAgent for iOS helps you identify mobile user experience problems before they affect your users. It also lets you receive business analytics data like the geographic distribution of your web page visitors and average session duration. Dynatrace lets you set up OneAgent for iOS with CocoaPods or Carthage, or you can set it up manually through Dynatrace to enable UEM monitoring for iOS apps. OneAgent for iOS is synonymous with "Mobile agent" in AppMon. See Mobile UEM in AppMon documentation for details." "OneAgent for Android - Correct Answer Dynatrace's mobile app support for Android. Use Dynatrace auto-instrumentation to set up user experience monitoring for your Android app, which automatically adds OneAgent to your app and instruments it without modifying the source code. Because auto-instrumentation modifies the byte-code of your mobile app after you generate the APK file, ensure that your instrumented app is signed with your Google Play certificate before you upload the instrumented APK to the Google Play store. OneAgent for Android lets you track visitors, actions, and PurePaths that are triggered by your Android app once you've enabled UEM for Android apps. OneAgent for Android is synonymous with "Mobile agent" in AppMon. See Mobile UEM in AppMon documentation for details." "OneAgent - Correct Answer Dynatrace OneAgent monitors the performance of the hosts in your application-deployment environment, along with all related processes. Based on your environment settings, Dynatrace OneAgent enables detailed performance monitoring and real user monitoring of your applications and their services. Changes to your applications, as well as infrastructure and performance problems, are reported to Dynatrace for performance monitoring." "Multi-dimensional baselining - Correct Answer There are a number of variables (or dimensions) that affect application performance—most notably, geographic region, OS, browser, connection type, and user action. These are the five dimensions that Dynatrace uses to evaluate application health. Each subset of cohorts is subject to a unique set of these variables so Dynatrace measures the health of and reports on each of these user subsets separately." "Monitoring environment - Correct Answer Includes all the dashboards, charts, reports, and other tools that Dynatrace makes available for the analysis of your application or applications. A monitoring environment is analogous to an analysis server that provides all your Dynatrace application-performance analysis functionality. You can set up multiple monitoring environments to group related entities for discrete analysis. For example, you might set up one monitoring environment to monitor and analyze the performance of your production clusters. You might set up a second environment that's dedicated to the performance of your developers' machines and a third environment for your staging servers. How you segment your monitoring environments is entirely up to you." "Monitoring candidate - Correct Answer A host (either a VMware virtual machine or an EC2 instance) that communicates with monitored hosts in your environment, but doesn't itself have Dynatrace OneAgent installed on it. It's recommended that you install Dynatrace OneAgent on all monitoring candidates to gain full visibility and complete monitoring capabilities. In Smartscape, a candidate is visualized with dashed circles and a generic host icon. Candidates are shown linked to relevant data centers. Each monitoring candidate is also listed on the Hosts page, within the Unmonitored category. Any inactive monitoring candidates (those that haven't communicated with a host for more than two hours) aren't included in Smartscape or listed on the Hosts page." "Mission Control - Correct Answer The proactive support for Dynatrace Managed that automatically solves many common maintenance and support challenges for you. Mission Control's proactive support provides fully automated management capabilities that keep Dynatrace Server secure, reliable, and up-to-date—all while saving you from administrative tasks like upgrades and troubleshooting. A dedicated 24x7 support team proactively handles health checks, scaling verification, upgrades, and any troubleshooting when you run into problems. This includes: Analyzing hardware utilization and alerting you if you need more resources. Addressing problems or incompatibilities with your Dynatrace Server—so you don't need to track and react to system events. Optimizing your Dynatrace Managed settings to ensure optimum performance and stability. Collecting the required log files for problem resolution." "Merged services monitoring - Correct Answer Monitoring of data from services of the same type and the same process group. A merged service is a service that aggregates multiple web-request services of the same process group that perform identical functions across separate cluster nodes. Service merging is available only for web-request services that perform the same function within the same process group, and so are effectively identical from a performance-monitoring perspective. A merged service appears in Dynatrace as a single service that contains all the data of all aggregated services. Say you have an Apache web server with several virtual host definitions (for example, , , and ). From the Apache perspective, these are independent virtual hosts. Therefore Dynatrace detects them as separate services. For your monitoring purposes however, you might want to view these services as a single merged service called Dynatrace web page. To take the guess work out of knowing which of your services are eligible for service merging, Dynatrace automatically identifies mergable services for you and displays them on the Merged service monitoring page (Settings > Server-side service monitoring > Merged service monitoring). Only services included in this list can be merged." "Log analytics - Correct Answer The intelligent evaluation of data-logging records that are produced by network devices, operating systems, applications, and other intelligent or programmable devices. Dynatrace log analytics provides direct access to the log content of all your system's mission-critical processes and enables you to quickly search for specific log messages. You can filter log content based on keywords or analysis timeframe, and even analyze multiple log files simultaneously—even when log files are stored across multiple hosts. Most significantly, Dynatrace artificial intelligence automatically correlates relevant log messages with any problems that are detected in your environment. Any relevant log messages associated with a problem are factored into that problem's root-cause analysis." "Key request - Correct Answer Key requests are requests that are of particular interest in your web-application environment because they're a critical measure of the success of your business (for example, a login request or a shopping-cart checkout request), because they provide vital technical functionality that your application relies on, or because they involve complex calculations. Dynatrace provides advanced monitoring functionality for such key requests so you can monitor them with extra care. Key requests feature long-term metric history and dedicated dashboard tiles for charting and direct access from your dashboard. Key requests are always alerted on, even when they contribute less than 1% of throughput. They also provide custom thresholds. Key requests are highlighted in the Key requests section of each service overview page. This visibility is particularly valuable for low-volume, high-importance requests that would otherwise appear at the bottom of the Top requests section of a service overview page." "Hyperlyzer - Correct Answer This Dynatrace multidimensional visual interface lets you analyze multiple dimensions of the top three findings of your application's usage. With Hyperlyzer, you can see details on where your users are located, what browser versions they're using, their operating systems, and the number of different user actions your application has received. The Hyperlyzer wheel interface enables you to quickly focus on specific dimensions of interest. Hyperlyzer data is based on detection rules, which can be configured separately for each application." "Host unit - Correct Answer The size of a host for billing purposes (based on amount of RAM). For full-stack monitoring, a host with 16 GB of RAM equates to 1 host unit. For cloud-infrastructure monitoring, a host with 16 GB of RAM equates to 0.3 of a host unit. For example, a host with memory size of 24 GB equates to 2 full-stack monitoring host units and .6 cloud-infrastructure monitoring host units." "External service - Correct Answer Any service called by your application or another service that isn't directly monitored by Dynatrace OneAgent is considered to be an external service. Dynatrace maintains awareness of external services when they send or receive requests from your monitored services and applications. Dynatrace doesn't however receive performance data related to external services. An exception to this rule is database services. If you have Dynatrace OneAgent installed on a machine from which JDBC calls are sent to your database, Dynatrace will provide a full spectrum of performance analysis related to the called database service (even when Dynatrace OneAgent isn't installed on the database server machine itself)." "Event - Correct Answer A manual action performed on a server in your environment. Events are reported by Dynatrace and, where applicable, correlated with detected problems. Examples of events include machine reboots, system shutdowns, process restarts, and new code deployments. Any manual action you perform on a server is an event, even if it's a regularly scheduled event." "Environment topology - Correct Answer A Smartscape visualization of the hosts, processes, services, applications, and data centers in your Dynatrace monitoring environment and the relationships between those entities. With no manual configuration, Smartscape auto-discovers all the components and dependencies of your entire technology stack end-to-end and visualizes them in an easy to understand environment topology map." "Environment ActiveGate - Correct Answer An ActiveGate that is bound to your environment, and thus only handles traffic from OneAgent instances that belong to the same environment as the ActiveGate. An Environment ActiveGate is downloaded from your Dynatrace environment and installed within your infrastructure. An Environment ActiveGate only handles traffic from OneAgent, not from other ActiveGates. An Environment ActiveGate can communicate to a Dynatrace server either directly or via a Cluster ActiveGate." "Duration - Correct Answer The amount of time a synthetic monitor or synthetic action waits before the web application is ready to initiate another user action." "Deep process monitoring - Correct Answer Dynatrace provides you with deep visibility into the performance of all the services that comprise your web application: web services, web containers, database requests, custom services, and more. You can even track service performance over time, with both historical and up-to-the-moment data." "Davis - Correct Answer The Dynatrace Artificial Virtual Intelligence System. Davis is the first digital performance assistant powered by artificial intelligence. Using an Amazon Alexa compatible device and Dynatrace artificial intelligence, you can ask Davis natural language questions about your Dynatrace environment using only your voice. The conversational interface brings Davis into the room with you, where he can serve as your virtual assistant. Davis provides data-driven answers and insights instead of raw data, and even learns who you are and customizes answers. You can also interact with Davis through a number of other services, including Slack, and the Davis web app." "Data center - Correct Answer From the perspective of Dynatrace Smartscape environment-topology mapping, a data center is either: A grouping of virtual machines running in an Amazon cloud instance. Dynatrace maps Availability Zones to your data center. Or a set of vCenter-based virtual hosts that transmit data to Dynatrace via a single ActiveGate. You may have multiple vCenter servers or standalone ESXi hosts associated with a single data center. Each virtual host within a data center must have Dynatrace OneAgent installed on it. You'll see at least one data center in Smartscape view if you have a ActiveGate installed. If you don't have a ActiveGate in your environment, Smartscape can't create a data center for your topology map. Note that Dynatrace provides real-world geographic location details for data centers—look for data center location details in Smartscape and on Host pages (in the Properties pane)" "Cluster ActiveGate - Correct Answer A Dynatrace component that provides secure and reliable communication with cloud-based Dynatrace cluster nodes. It is downloaded from your Dynatrace Managed cluster and installed within your infrastructure. Similar to a proxy, ActiveGate reduces bandwidth requirements by encrypting and compressing network communication. It also provides monitoring of virtual infrastructure. Stopping or disabling ActiveGate reduces the monitoring capabilities of hosts that use a Cluster ActiveGate to communicate with Dynatrace clusters." "Cluster - Correct Answer The Dynatrace monitoring infrastructure. A cluster contains one or more cluster nodes that are set up using the Dynatrace Managed installer. After successful installation, each Dynatrace Managed cluster node runs a Dynatrace Server, an ActiveGate, and one instance of Cassandra, Elasticsearch, and NGINX. Each cluster also provides a web-based management interface called a Cluster Management Console." "Crash analysis - Correct Answer Determining the root causes of a process crash. Dynatrace accelerates crash analysis by providing a process crash entry for each affected process and monitored host. Details available for crash analysis may include a native core dump, a Java core dump, or an abnormal program exit due to exceptions. Dynatrace also provides access to additional crash artifacts, such as hs_err_pid files for Java crashes, text files providing Linux and Windows core dump analysis, and files containing the .NET, Java, or N exceptions that are potentially responsible for crashes." "Cluster Management Console (CMC) - Correct Answer The web-based user interface that manages a single Dynatrace Managed cluster. The CMC allows you to: View the deployment status and configure your Dynatrace Managed cluster. Manage cluster nodes and ActiveGates. Manage your monitoring environments. Create user accounts and groups. View licensing information and consumption status. View audit log and cluster events." "Browser monitor - Correct Answer The equivalent of a simulated user visiting your application using a modern web browser. Browser monitors can be configured to run from any of our global locations at a frequency of up to once every 5 minutes. Browser monitors alert you when your application is inaccessible from the Internet or when baseline performance degrades significantly." "Browser clickpath - Correct Answer A simulated user visit that monitors your application's business critical workflows. Use the Dynatrace recorder to record an exact sequence of clicks and user input that you're interested in monitoring for availability and performance. Once you've captured the mouse clicks and additional user actions that you want your browser clickpath to include, your synthetic monitor runs automatically at regular intervals to test your site's availability and functionality." "Application - Correct Answer A web application consists of web pages that are served by web servers and web containers, for example Tomcat. A web or mobile application is built upon services that process requests like web requests, web service calls, and messaging. Within Dynatrace, the term application refers to the front-end part that you can access via a browser or a mobile app. Dynatrace monitors all of your application's services, processes, and infrastructure. By evaluating all components collectively, Dynatrace pinpoints exactly how each service contributes to the performance of your application. For example, in Java monitoring, the host, JVM, and processes are seen as a whole. Dynatrace monitors all the individual components that applications are built upon: web requests, database requests, processes, services, and more. It's these individual components working together that collectively deliver what your end users view as a complete application. Dynatrace identifies and tracks each of these individual application components at a highly granular level. Dynatrace doesn't simply identify that a service is running on a server in a process but rather identifies all the details of these components. For example, Dynatrace can show you which of your web services is running on your Tomcat application server and how your Tomcat server's performance is affected by its host, or even your VMware vCenter server. In this way, Dynatrace gives you insight into the performance of your unique application stack, including all its components and connections." "What we can see from Service quality reports? - Correct Answer Overall Dynatrace score Your overall Dynatrace score is an average of the application, services, and infrastructure scores for your environment Application score average of your application Apdex value and the percentage of user actions that are not affected by problems. Services Score percentage of service calls that were successful and unaffected by problems. Infrastructure percentage of host time during which no problems were encountered." "What is the maximum time range of Smartscape data display - Correct Answer 72 hours" "How to share your Dashboard - Correct Answer Using Share button" "How Dynatrace defines Database service name - Correct Answer It identifies the name of the database or schema, the database vendor and the IP address/port of the database" "How Dynatrace defines services name - Correct Answer Web server name, Context root, and Web application ID."
