Viewing Operator metrics

The Custom Metrics Autoscaler Operator exposes ready-to-use metrics that it pulls from the on-cluster monitoring component. You can query the metrics by using the Prometheus Query Language (PromQL) to analyze and diagnose issues. All metrics are reset when the controller pod restarts.

Accessing performance metrics

You can access the metrics and run queries by using the OKD web console.

Procedure

  1. Select the Administrator perspective in the OKD web console.

  2. Select Observe → Metrics.

  3. To create a custom query, add your PromQL query to the Expression field.

  4. To add multiple queries, select Add Query.

Provided Operator metrics
