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

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

By default, only requests at the service level are imported by the telemetry provider.

To import specific key requests you can follow these steps.

Component Creation

Create a new component of type Web Application for each key request you want to import. This allows tracking response time, throughput, and error rates separately.

You can use the following yaml file as an example and customize it to suit your needs.

name: KeyRequestA
description: The key request A for my application
componentType: Web Application
properties:
 dynatrace: 
  type: SERVICE_METHOD
  id: SERVICE_METHOD-D4BCC949D5DD656A

In order to instruct Akamas to import a specific key request you just need to change the id field of the yaml above to the one that matches your key request on Dynatarce.

To obtain that ID open the analysis page for the request as in the example below, take note of the URL of the page, and look for the SERVICE_METHOD keyword. The id is the one starting with SERVICE_METHOD and ending before the character %14

Considering the example below the id is SERVICE_METHOD-D4BCC949D5DD656A

Telemetry instance setup

Create a telemetry instance for your system using the yaml specified below as an example and modify it to provide your Dynatrace account and credentials. This will instruct Akamas to use key request metrics instead of service metrics.

provider: Dynatrace
config:
 url: https://<my-account>.dynatrace.com/
 token: <my-token>
metrics:
  - metric: requests_response_time
    datasourceMetric: builtin:service.keyRequest.response.time
    scale: 0.001    
    defaultValue: 0.0
    staticLabels:
      provider: dynatrace
  - metric: requests_throughput
    datasourceMetric: builtin:service.keyRequest.errors.server.successCount
    scale: 0.0166666666666666666666666666666
    defaultValue: 0.0
    staticLabels:
      provider: dynatrace        
  - metric: requests_error_rate
    datasourceMetric: builtin:service.keyRequest.errors.server.rate
    scale: 0.01
    defaultValue: 0.0
    staticLabels:
      provider: dynatrace
