Dynatrace GitHub Action

This GitHub Action enables CI/CD workflows to report events and metrics to a Dynatrace monitoring environment.

Usage

The action configuration must specify the Dynatrace url as well as an API token to be able to send information into a Dynatrace environment. We strongly advise to use GitHub repository placeholders for both information here to prevent the exposure of secrets in your repository!

The url must contain a Dynatrace domain, e.g.: https://{your-environment-id}.live.dynatrace.com.

The token must contain a Dynatrace API v2 token with 'Ingest metrics' and/or 'Ingest events' scope enabled, as shown below:

Please note how metrics and events is configured as a string containing YAML code - this allows to send more than one metric or event at once. To send a metric, configure a job step like the following:

- name: Build count
  uses: dynatrace-oss/dynatrace-github-action@v9
  with:
    url: '${{ secrets.DT_URL }}'
    token: '${{ secrets.DT_TOKEN }}'
    metrics: |
      - metric: "github.metric1"
        value: "1.0"
        dimensions:
          project: "${{ github.repository }}"
          branch: "${{ github.ref }}"
          event: "${{ github.event_name }}"
          owner: wolfgang

Analyze the resulting CI/CD pipeline metric within Dynatrace, as shown below:

You can also send Dynatrace events from workflows, same as metric. See below how an event is configured within the events section. The standard entity selector query is used to push the event on a selected entity or onto a cohort of entities e.g.: a tagged set of services. See the Dynatrace help page on entity selectors. See some example entity selectors below:

• type(host),tag(prod) Selects all hosts with a tag 'prod'.
• type(service),entityName(login) Selects services with the name 'login'

For example, to send an event whenever a job has failed:

steps:
  - name: checkout
    uses: actions/checkout@v2
  - name: build
    run: this-will-fail
  - name: Notify Dynatrace on Build Failed
    if: failure()
    uses: dynatrace-oss/dynatrace-github-action@v9
    with:
      url: '${{ secrets.DT_URL }}'
      token: '${{ secrets.DT_TOKEN }}'
      events: |
        - title: "Build failed"
          type: CUSTOM_INFO
          entitySelector: type(host),entityName(myHost)
          properties:
            description: "Branch ${{ github.ref }} failed to build"
            source: GitHub
            project: "${{ github.repository }}"
            branch: "${{ github.ref }}"
            event: "${{ github.event_name }}"
            owner: ${{ github.repository_owner }}

In another example, a deployment event can be sent onto a specific entity. In this example the event is sent to a mobile app whenever the Android GitHub Action build workflow succeeded:

steps:
  - name: checkout
    uses: actions/checkout@v2
  - name: build
    run: this-will-fail
  - name: Notify Dynatrace on Build Failed
    if: failure()
    uses: dynatrace-oss/dynatrace-github-action@v9
    with:
      url: '${{ secrets.DT_URL }}'
      token: '${{ secrets.DT_TOKEN }}'
      events: |
        - type: CUSTOM_DEPLOYMENT
          title: Mobile app version deployment failed
          entitySelector: type(MOBILE_APPLICATION),entityId(MOBILE_APPLICATION-C061BED4799B41C5)
          properties:
            source: GitHub
            deploymentName: "GitHub Action"
            deploymentVersion: "${{ github.ref }}"
            deploymentProject: "${{ github.repository }}"
            remediationAction: "None"
            ciBackLink: "https://github.com/${{ github.repository }}"
            project: "${{ github.repository }}"
            branch: "${{ github.ref }}"
            event: "${{ github.event_name }}"
            owner: wolfgang
