Chetan opened this PR https://github.com/apache/incubator-openwhisk/pull/4327 which fixes an issue with using historgrams for some metrics where gauges should be used instead. There was a brief exchange on slack [1, 2] in favor of this change.
The PR has two commits, the first I think is fine and non-breaking. The second change as Chetan notes is "sort of a breaking change" but I agree which him in that the existing histograms do not look very useful in some cases. If you're interested in this PR please have a look and comment, otherwise will apply lazy consensus to merge it. -r [1] https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552009389150600?thread_ts=1551982869.141200&cid=C3TPCAQG1 [2] https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552014636150800?thread_ts=1551982869.141200&cid=C3TPCAQG1
