QUESTIONS AND SOLUTIONS FULL REVIEW

●● Dynatrace OneAgent
Answer: A host-based agent that is installed on each monitored host.
OneAgent automatically instruments processes, collects metrics (CPU,
memory, network, etc.), traces transactions end-to-end (PurePath), and
reports data to the Dynatrace cluster (directly or via an ActiveGate).
●● Dynatrace ActiveGate
Answer: A gateway component that acts as a secure proxy between
OneAgents and the Dynatrace cluster. ActiveGates route OneAgent
traffic (especially from isolated networks) to the cluster, and also
execute special tasks such as cloud monitoring, Synthetic monitor
execution, and z/OS monitoring.
●● Environment ActiveGate vs Cluster ActiveGate
Answer: Environment ActiveGates are installed by customers to serve a
specific environment (tenant) and handle OneAgent routing, synthetic,
and integration tasks. Cluster ActiveGates are built-in to Dynatrace
Managed cluster nodes and handle cluster-level communication. In
Dynatrace SaaS you only use Environment ActiveGates.
,●● Dynatrace cluster node (Managed)
Answer: A Dynatrace Managed cluster node is a server that runs the
Dynatrace cluster software, including components for processing,
storing, and querying monitoring data. Each node includes services and
storage and an embedded ActiveGate.
●● Cluster architecture and replication
Answer: Dynatrace Managed clusters require at least 3 nodes for
production to ensure high availability. Data is replicated across nodes so
that if one node fails, data remains available. All cluster nodes are active
and share the load.
●● Mission Control (Dynatrace Managed)
Answer: A Dynatrace cloud service that connects with Dynatrace
Managed clusters to provide license management, usage reporting,
health monitoring, and remote support. If connectivity is lost, license
overages are disabled after 14 days.
●● Data encryption in transit
Answer: All communication between OneAgent, ActiveGate, and
Dynatrace cluster is encrypted via TLS.
●● OneAgent to ActiveGate connection port
,Answer: OneAgent connects to an Environment ActiveGate on port
9999 (HTTPS).
●● ActiveGate to Cluster connection ports
Answer: Environment ActiveGates communicate with the Dynatrace
cluster typically on port 443 or 8443.
●● Network zones
Answer: A Network Zone is a logical label that helps control and
optimize OneAgent traffic routing by assigning it to nearby ActiveGates.
●● Multi-environment support
Answer: Dynatrace Managed allows multiple monitoring environments
(tenants) on one cluster, each logically separated with its own data.
●● Embedded ActiveGate (Managed cluster)
Answer: Each Dynatrace Managed cluster node includes an embedded
ActiveGate for cluster-level communication.
●● Update cadence (SaaS vs Managed)
Answer: SaaS clusters are updated by Dynatrace automatically, while
Managed clusters are updated manually by the administrator.
●● OneAgent update mechanism
, Answer: OneAgents can be upgraded centrally by the cluster,
automatically or manually depending on settings.
●● ActiveGate update mechanism
Answer: Environment ActiveGates support auto-update when configured
or can be updated manually.
●● High availability for ActiveGates
Answer: Multiple ActiveGates can be installed in the same zone for
failover and load balancing.
●● Scaling Dynatrace Managed
Answer: Add nodes with similar specs or increase node resources to
scale Dynatrace Managed clusters.
●● Data storage (Dynatrace cluster)
Answer: Dynatrace cluster nodes use Cassandra for metrics and
Elasticsearch for events/traces.
●● SaaS data centers vs Managed
Answer: In SaaS, data is stored in Dynatrace cloud regions. In Managed,
data resides on your own nodes.
●● Mission Control connectivity requirement
