Dynatrace Associate Exam

Dynatrace Associate Exam Dynatrace OneAgent - 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. 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. Dynatrace OneAgent : Supported technologies and versions - You can install OneAgent on the following Linux, Unix, Windows, and z/OS operating systems. Real User Monitoring - Real User Monitoring (RUM) is one of the two fundamental constituents of Digital Experience Monitoring (DEM), the other one being Synthetic monitoring. DEM is defined by Gartner as an availability and performance monitoring discipline that supports the optimization of the operational experience and behavior of a digital agent, human or machine, as it interacts with enterprise applications and services. Dynatrace RUM gives you the power to know your customers by providing performance analysis in real time. This includes all user actions taken and how the various actions impact performance. You can also easily identify problems or errors that occurred as well as user experience ratings, geolocation breakdowns and much more. You can also gain insight into the behavior of your users. This among others includes the number of customers who return to your site. With Dynatrace RUM, you have the context over time and immediate analysis to the complete picture of your end user experience. Application and infrastructure monitoring - Dynatrace application and infrastructure monitoring is provided via installation of a single Dynatrace OneAgent on each monitored host in your environment. OneAgent is licensed on a per-host basis (virtual or physical server). However, not all hosts are of equal size. Larger hosts consume more host units than do smaller-sized hosts. We use the amount of RAM on a monitored server as a measuring stick to determine the size of a host (i.e., how many host units it comprises). The advantage of this approach is its simplicity—we don't take technology-specific factors into consideration (for example, the number of JVMs or the number of microservices that are hosted on a server). It doesn't matter if a host is .NET-based, Java-based, or something else. You can have 10 JVMs or 1,000 JVMs; such factors don't affect the amount of monitoring that an environment consumes. OneAgent can operate in two different modes. By default, OneAgent operates in full-stack mode. Alternatively, you can use infrastructure monitoring mode to monitor hosts that don't require full-stack visibility. Infrastructure mode consumes fewer host units than full-stack mode. Digital Experience Monitoring - In addition to the application and infrastructure monitoring provided by OneAgent, you may also require Dynatrace Synthetic Monitoring, Real User Monitoring, and Session Replay. These capabilities are consumed based on Digital Experience Monitoring units, otherwise known as DEM Units. The amount of DEM Units you need depends on how many synthetic monitors you want to run and how many user sessions you need to monitor. The table below explains the rate at which DEM Units are consumed per each capability type and unit of measure. Synthetic actions and requests - A browser monitor or browser clickpath "synthetic action" is an interaction with a synthetic browser that triggers a web request that includes a page load, navigation event, or action that triggers an XHR or Fetch request. Browser monitors perform a single synthetic interaction (for example, measuring the performance and availability of a single URL) and consume one synthetic action per execution. Clickpath monitors are sequences of pre-recorded synthetic actions. Clickpaths consume one action per each interaction that triggers a web request. Scroll downs, keystrokes, or clicks that don't trigger web requests aren't counted as actions. HTTP monitor - consists of one or multiple HTTP(S) requests (for example, GET, POST, HEAD requests). Each request executed by an HTTP monitor equates to one synthetic request. Custom vs built-in
