Description of problem:
While running the diagnostics tool for 'AggregatedLogging' I could see following error.

I came across bugzilla [1] & [2]. Bugzilla [1] has been marked as duplicate of bugzilla[2]. Fix for bugzilla[2] has been shiped with version 3.11.129. However I am still able to see the issue existing in Openshift version 3.11.161.
