What are the 4 parts included in the plugin.json definition for ActiveGate plugins? - -
Metadata, UI, Metrics, Configuration
-How are ActiveGate plugins licensed? - -The plugin SDK is free. Dynatrace partners
can develop plugin for you, will depend on contract. Whatever custom metrics are used
will be charged.
-How frequently do ActiveGate plugins execute? - -Once per minute
-Can you run multiple endpoints in a single ActiveGate plugin module? - -Yes
-What kind of ActiveGate executes ActiveGate plugins? - -Environment ActiveGate
-Can you execute ActiveGate plugins using an Environment ActiveGate that's
configured for multi-environment support? - -No
-Where can you view results from plugin-monitoring? - -Technology overview page
-What is a "device group"? - -A technology tile that derives its data from an ActiveGate
plugin.
-Why would you set up "key metrics" for an ActiveGate plugin? - -Define important
metrics to be displayed in technology overview page.
-What is the favicon property in the plugins.json definition? - -Allows you to define
your own custom icon for device groups!
,-What can device groups represent? - -Clusters, regions, groups of servers, etc.
-What is a custom device group entity? - -Bind metrics and properties to monitor
device group metrics
-How do you define the type and look of charts of ActiveGate plugins? - -plugin.json
-What is pgmetrics in plugins.json for ActiveGate plugins? - -Section that allows you to
define custom device metrics.
-Does Dynatrace AI baseline the metrics of your custom devices? - -Yes!
-How does Dynatrace create problems from custom devices (ActiveGate plugin)? - -
Metric threshold violation in JSON definition. (Automatically sends events, not
problems)
-How do you manually generate problems for your ActiveGate plugins? - -Python API -
raise performance, availability, error, and resource contention problems
-Does Dynatrace automatically distribute plugins between Dynatrace server and
ActiveGates? - -No, you need to deploy them on ActiveGate and upload them to server.
-In general, what is the point of plugins.json (ActiveGate plugins)? - -Define how data
is presented in the Dynatrace UI.
-In general, what is the point of Python files for ActiveGate plugins? - -Define
additional events, create custom properties.
-How many Cluster Management Consoles are there per cluster? - -One per cluster.
, -What is each managed cluster associated with? - -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? - -Dynatrace
Server, Cassandra, Elasticsearch, Embedded ActiveGate, NGINX
-What can you do with CMC? - -Create user accounts and groups, add new cluster
nodes, add new monitoring environments.
-How many nodes does Dynatrace recommend per cluster? - -At least 3 - data is
replicated across nodes
-What percentage of managed cluster nodes does Dynatrace need to be running? - -
Majority (50%+)
-What does Dynatrace recommend for latency between managed cluster nodes? - -
10ms or less
-Is transaction data (call stacks, database statements, code-level visibility etc.)
replicated across managed cluster nodes? - -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? - -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? - -At least 3 data centers (1
can fail)
-Why does Dynatrace recommend that each managed cluster node be deployed on a
separate physical disk? - -To prevent loss of monitoring data.
