Telemetry metrics error in a cluster without enough resources

XMLWordPrintable

    • IDH Sprint 1.11
    • Medium

      Description of problem:

      Spawning a medium size jupyter container, in a cluster without enough resources, is causing the notebook pod to remain in Pending state for 10 minutes, but the metrics cpu_requests_runtime and running cpu_limits_runtime are counting it as if it was running.

      Prerequisites (if any, like setup, operators/versions):

      rhods version v1.10.0-6

      Steps to Reproduce

      1. install RHODS in a cluster without enough resources and to have a pod in a pending state
      2. Go to openshift-monitoring project
      3. Write the metrics in prometheus cpu_requests_runtime and running cpu_limits_runtime

      Actual results:

      A pod in a pending state is counting into the metric.

      Expected results:

      Pods have to be counted when they are in a running state.

      Reproducibility (Always/Intermittent/Only Once):

      Always
