Changing log level for IBM Storage Scale DAS components

Change the log level collection for IBM Storage Scale DAS components.

You can change log levels for the following IBM Storage Scale DAS components:

• NooBaa component logs
• IBM Storage Scale DAS operator and IBM Storage Scale DAS endpoint logs

Change the verbosity of openshift-storage namespace for noobaa component logs

For the openshift-storage namespace, the following log levels are available.

• default_level
• all
  Note: The default_level is 0 and all is 5.

By default, the log level for the openshift-storage namespace is set to default_level. To increase the verbosity of logs for the NooBaa component, change the log level to a higher value (0 is set as default):

Note: The noobaa command is available from the RedHat ODF package as a separate rpm.

For example:

noobaa system set-debug-level 3

INFO[0000] ✅ Exists: NooBaa "noobaa"

INFO[0000] ✅ Exists: Service "noobaa-mgmt"

INFO[0000] ✅ Exists: Secret "noobaa-operator"

INFO[0000] ✅ Exists: Secret "noobaa-admin"

Debug level was set to 3 successfully

Debug level is not persistent and is only effective for the currently running core and endpoints pods

Change the log level for das-operator and das-endpoint pods

For the das-operator and das-endpoint pods, the following log levels are available.

• INFO
• DEBUG
• ERROR
• WARN

As an IBM Storage Scale DAS administrator, change the log level for das-operator and das-endpoint pods as follows:

1. Change the context to the ibm-spectrum-scale-das namespace.

   oc project ibm-spectrum-scale-das

2. Change the LOG_LEVEL environment variable under the spec section for das-operator-controller-manager spec.

   oc edit deployment ibm-spectrum-scale-das-controller-manager

   For example,

   spec:
   ...
   ...
      spec:
         containers:
         ...
         ...
            env:
            - name: LOG_LEVEL
              value: DEBUG

Once the log level is changed for the IBM Storage Scale DAS operator and IBM Storage Scale DAS endpoint, it automatically gets applied to the das-endpoint pods, when the das-operator reconciles the das-endpoint pods with the changed log level.
