Create Dynatrace telemetry instances

The installed provider is shared with all users of your Akamas installation and can monitor many different systems, by configuring appropriate telemetry provider instances.

To create an instance of the Dynatrace provider, build a YAML file (instance.yml in this example) with the definition of the instance:

# Dynatrace Telemetry Provider Instance
provider: Dynatrace
config:
  url: https://wuy711522.live.dynatrace.com
  token: XbERgThisIsAnExampleToken

Then you can create the instance for the system using the Akamas CLI:

akamas create telemetry-instance instance.yml system

Configuration options

When you create an instance of the Dynatrace provider, you should specify some configuration information to allow the provider to correctly extract and process metrics from Dynatrace.

You can specify configuration information within the config part of the YAML of the instance definition.

Required properties

• url - URL of the Dynatrace installation API (see https://www.dynatrace.com/support/help/extend-dynatrace/dynatrace-api/ to retrieve the URL of your installation)

• token - A Dynatrace API Token with the proper permissions

Collect additional metrics

You can collect additional metrics with the Dynatrace provider by using the metrics field:

config:
  url: https://wuy71982.live.dynatrace.com
  token: XbERgkKeLgVfDI2SDwI0h
metrics:
- metric: "akamas_metric"                     # extra akamas metrics to monitor
  datasourceMetric: builtin:host:new_metric   # query to execute to extract the metric
  labels:
  - "method"      # the "method" label will be retained within akamas

Configure a proxy for Dynatrace

In the case in which Akamas cannot reach directly your Dynatrace installation, you can configure an HTTP proxy by using the proxy field:

config:
  url: https://wuy71982.live.dynatrace.com
  token: XbERgkKeLgVfDI2SDwI0h
  proxy:
    address: https://dynaproxy  # the URL of the HTTP proxy
    port: 9999                  # the port the proxy listens to

Telemetry instance reference

This section reports the complete reference for the definition of a telemetry instance.

provider: Dynatrace  # this is an instance of the <name> provider
config:
  url: https://wuy71982.live.dynatrace.com
  token: XbERgkKeLgVfDI2SDwI0h
  proxy:
    address: https://dynaproxy # the URL of the HTTP proxy
    port: 9999            # the port the proxy listens to
    username: myusername  # http basic auth username if necessary
    password: mypassword  # http basic auth password if necessary
  tags:
    Environment: Test       # dynatrace tags to be matched for every component

metrics:
- metric: "cpu_usage"  # this is the name of the metric within Akamas
  # The dynatrace metric name
  datasourceMetric: "builtin:host.cpu.usage"
  extras:
      mergeEntities: true  # instruct the telemetry to aggregate the metric over multiple entities
  aggregation: avg  # The aggregation to perform if the mergeEntities property is set to true

This table shows the reference for the config section within the definition of the Dynatrace provider instance:

Field	Type	Value restrictions	Required	Default Value	Description
url	String	It should be a valid URL	Yes		The URL of the Dynatrace installation API (see the official reference)
token	String		Yes		The Dynatrace API Token the provider should use to interact with Dynatrace. The token should have sufficient permissions.
proxy	Object	See Proxy options reference	Yes		The specification of the HTTP proxy to use to communicate with Dynatrace.
pushEvents	String	true, false	No	true	If set to true the provider will inform dynatrace of the configuration change event which will be visible in the Dynatrace UI.
tags	Object		No		A set of global tags to match Dynatrace entities. The provider uses these tags to apply a default filtering of Dynatrace entities for every component.

Proxy options reference

This table reports the reference for the config → proxy section within the definition of the Dynatrace provider instance:

Field	Type	Value restrictions	Required	Default value	Description
address	String	It should be a valid URL	Yes		The URL of the HTTP proxy to use to communicate with the Dynatrace installation API
port	Number (integer)	1 <port<65535	Yes		The port at which the HTTP proxy listens for connections
username	String		No		The username to use when authenticating against the HTTP proxy, if necessary
password	String		No		The username to use when authenticating against the HTTP proxy, if necessary

Metrics options reference

This table reports the reference for the metrics section within the definition of the Dynatrace provider instance. The section contains a collection of objects with the following properties:

Field	Type	Value Restrictions	Required	Default value	Description
metric	String	It must be an Akamas metric	Yes		The name of an Akamas metric that should map to the new metric you want to gather
datasourceMetric	String	A valid Dynatrace metric	Yes		The Dynatrace query to use to extract metric
labels	Array of strings	-	No		The list of Dynatrace labels that should be retained when gathering the metric
staticLabels	Key-Value	-	No		Static labels that will be attached to metric samples

Use cases

This section reports common use cases addressed by this provider.

Collect system metrics

Check the Linux optimization pack for a list of all the system metrics available in Akamas.

As a first step to start extracting metrics from Dyntrace, generate your API token and make sure it has the right permissions.

As a second step, choose a strategy to map your Linux component (MyLinuxComponent) with the corresponding Dyntrace entity.

Let’s assume you want to map by id your Dynatrace entity, you can find the id in the URL bar of a Dyntrace dashboard of the entity:

Grab the id and add it to the Linux component definition:

name: MyLinuxComponent
description: this is a Linux component
properties:
  dynatrace:
    id: HOST-A987D45512ABCEEE

You can leverage the name of the entity as well:

name: MyLinuxComponent
description: this is a Linux component
properties:
  dynatrace:
    name: Host1

As a third and final step, once the component is all set, you can create an instance of the Dynatrace provider and then build your first studies:

name: Dynatrace
config:
  url: https://my_dyna_installation_url
  token: MY_DYNA_TOKEN
