Can you run multiple endpoints in a single ActiveGate plugin module? - ANSWER Yes
What kind of ActiveGate executes ActiveGate plugins? - ANSWER Environment
ActiveGate
Can you execute ActiveGate plugins using an Environment ActiveGate that's configured
for multi-environment support? - ANSWER No
Where can you view results from plugin-monitoring? - ANSWER Technology overview
page
What is a "device group"? - ANSWER A technology tile that derives its data from an
ActiveGate plugin.
Why would you set up "key metrics" for an ActiveGate plugin? - ANSWER Define
important metrics to be displayed in technology overview page.
What is the favicon property in the plugins.json definition? - ANSWER Allows you to
define your own custom icon for device groups!
What can device groups represent? - ANSWER Clusters, regions, groups of servers,
etc.
What is a custom device group entity? - ANSWER Bind metrics and properties to
monitor device group metrics
How do you define the type and look of charts of ActiveGate plugins? - ANSWER
plugin.json
What is pgmetrics in plugins.json for ActiveGate plugins? - ANSWER Section that
allows you to define custom device metrics.
Does Dynatrace AI baseline the metrics of your custom devices? - ANSWER Yes!
How does Dynatrace create problems from custom devices (ActiveGate plugin)? -
ANSWER Metric threshold violation in JSON definition. (Automatically sends events, not
problems)
How do you manually generate problems for your ActiveGate plugins? - ANSWER
Python API - raise performance, availability, error, and resource contention problems
Does Dynatrace automatically distribute plugins between Dynatrace server and
ActiveGates? - ANSWER No, you need to deploy them on ActiveGate and upload them
to server.
In general, what is the point of plugins.json (ActiveGate plugins)? - ANSWER Define
how data is presented in the Dynatrace UI.
In general, what is the point of Python files for ActiveGate plugins? - ANSWER Define
additional events, create custom properties.
How many Cluster Management Consoles are there per cluster? - ANSWER One per
cluster.
What is each managed cluster associated with? - ANSWER One or more nodes (with
Dynatrace server instances), one or more monitored environments (with OneAgent),
one cluster management console.
What are the components included in the Dynatrace Managed installer? - ANSWER
Dynatrace Server, Cassandra, Elasticsearch, Embedded ActiveGate, NGINX
What can you do with CMC? - ANSWER Create user accounts and groups, add new

How many nodes does Dynatrace recommend per cluster? - ANSWER At least 3 - data
is replicated across nodes
What percentage of managed cluster nodes does Dynatrace need to be running? -
ANSWER Majority (50%+)
What does Dynatrace recommend for latency between managed cluster nodes? -
ANSWER 10ms or less
Is transaction data (call stacks, database statements, code-level visibility etc.) replicated
across managed cluster nodes? - ANSWER No - evenly distributed across all nodes
If you're distributing managed cluster nodes across separate data centers, what is the
max amount of nodes that Dynatrace recommends per data center? - ANSWER No
more than 2 nodes per data center
If you're distributing managed cluster nodes across separate data centers, what is the
min amount of data centers that Dynatrace recommends? - ANSWER At least 3 data
centers (1 can fail)
Why does Dynatrace recommend that each managed cluster node be deployed on a
separate physical disk? - ANSWER To prevent loss of monitoring data.
Why does Dynatrace recommend deploying managed cluster nodes on systems with
the same hardware characteristics? - ANSWER To minimize performance loss
What should you keep in mind when building your manged cluster? - ANSWER Build
cluster with additional capacity and possible node failure in mind.
What happens when a managed cluster node fails? - ANSWER NGINX automatically
load balances and redirects all OneAgent traffic to the remaining working nodes.
Why would you use Dynatrace Managed deployment scenario 1: Basic setup? -
ANSWER If you want your managed cluster to only be accessible internally. [Show Less]
