OpenTelemetry observability

How to standardize access to OpenTelemetry observability data

Using OpenTelemetry with Keptn metrics

Keptn metrics can be exposed as OpenTelemetry (OTel) metrics via port 9999 of the KLT metrics-operator.

To expose OTel metrics:

Be sure that the EXPOSE_KEPTN_METRICS environment variable in the metrics-operator manifest is set to true, which is the default value.
Define a KeptnConfig CRD that has the spec.OTelCollectorUrl field populated with the URL of the OpenTelemetry collector.

To access the metrics, use the following command:

kubectl port-forward deployment/metrics-operator 9999 -n keptn-lifecycle-toolkit-system

You can access the metrics from your browser at: http://localhost:9999
