I opened the unused envar in https://github.com/openshift/origin-metrics/pull/271

And I am lowering the priority of this, its really a non-issue aside from some potential confusion over why an envar is there that is not used.

PR is merged, set status to verified.

Comment 6 Peng Li 2016-12-02 08:43:34 UTC

User won't see this env var and won't set it correspondingly.
