Environment

• Red Hat OpenShift Container Platform
  • 3.4
  • 3.5
  • 3.6

Issue

• Whats wrong with hawkular-metrics
• How do I enable debug logging for hawkular-metrics?
• I need more information from the hawkular-metrics pod

Resolution

• To enable debug logging for the hawkular-metrics component, you will need to modify the replicationController (RC) for hawkular-metrics and add an environment variable with the name ADDITIONAL_LOGGING and the value of org.hawkular.openshift.auth=DEBUG
  • You can manually edit the rc oc edit rc hawkular-metrics and add that to the file or use the following command to drop it into place:

oc env rc/hawkular-metrics ADDITIONAL_LOGGING="org.hawkular.metrics=DEBUG,org.hawkular.alerts=DEBUG"

• After you add this environment variable you should scale your hawkular-metrics pod down to 0 and then back up to 1.

oc scale rc hawkular-metrics --replicas=0
oc scale rc hawkular-metrics --replicas=1

Diagnostic Steps

To verify that the variable was added, you can check the yaml of the RC or the pod. You can run the following command to do so:

oc get rc hawkular-metrics -o yaml | grep LOGGING -B10 -A 5
