Restore Keptn wildcard subscriptions

By default, the dynatrace-service subscribes to all sh.keptn events using the wildcard subscription sh.keptn.*. This allows the service to react to events as detailed in Feature overview.

If you have changed this via Keptn Uniform and want to restore the default of sh.keptn.*, this can be achieved using the Keptn API. In the future Keptn might introduce a way to restore the default via the Keptn Uniform UI.

Get all subscriptions for the dynatrace-service

Go to Keptn API / controlPlane and query the GET /uniform/registration endpoint with the parameter name=dynatrace-service. This should return a payload like the one below:

[
  {
    "id": "4b4d28a8f3bf811aa735f9531bae6bebf0df0f78",
    "name": "dynatrace-service",
    "metadata": {
      "hostname": "<some hostname>",
      "integrationversion": "0.20.0",
      "distributorversion": "0.9.0",
      "location": "control-plane",
      "kubernetesmetadata": {
        "namespace": "<some namespace>",
        "podname": "dynatrace-service-f645c8db5-bg4rr",
        "deploymentname": "dynatrace-service"
      },
      "lastseen": "2022-01-18T12:00:43.744Z"
    },
    "subscription": {
      "topics": null,
      "status": "",
      "filter": {
        "project": "",
        "stage": "",
        "service": ""
      }
    },
    "subscriptions": null
  }
]

Find the service with the correct version (if there is more than one) and copy the integrationID - in this case it would be 4b4d28a8f3bf811aa735f9531bae6bebf0df0f78 for version 0.20.0.

Here, no subscriptions are available (subscriptions: null) because they were deleted previously.

Optional: Query available subscriptions for an integration

In case you see at least one subscription, these can be queried via GET /uniform/registration/{integrationID}/subscription with the correct integrationID from the last step.

This will return any subscriptions set up via Keptn Uniform, such as:

[
  {
    "id": "6ea2d86e-d6fa-4b52-a487-28cf4e4b2161",
    "event": "sh.keptn.event.get-sli.triggered",
    "filter": {
      "projects": [],
      "stages": [],
      "services": []
    }
  }
]

Optional: Delete a subscription for an integration

If you have an invalid subscription, then delete it via DELETE /uniform/registration/{integrationID}/subscription/{subscriptionID} using the correct integrationID from above, as well as the correct subscriptionID from the last step.

Add a new default subscription

If you want to restore the default subscription for the dynatrace-service, use POST /uniform/registration/{integrationID}/subscription together with the correct integrationID from above and payload below:

{
  "filter": {
      "projects": [],
      "stages": [],
      "services": []
  },
  "event": "sh.keptn.>"
}
