Tim Armstrong updated IMPALA-8963:
----------------------------------
Priority: Minor (was: Major)
> Consider exposing histogram metrics properly as prometheus histograms
> ---------------------------------------------------------------------
>
> Key: IMPALA-8963
> URL: https://issues.apache.org/jira/browse/IMPALA-8963
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Tim Armstrong
> Priority: Minor
> Labels: observability
>
> IMPALA-8946 pointed out that we didn't correctly expose our metrics as
> histograms. Histogram metrics are meant to expose enough of the histogram
> state that prometheus can do additional computations on it. See
> https://prometheus.io/docs/practices/histograms/.
> We could consider exposing the histograms in this way so that there's more
> flexibility about additional computations we can do on the histograms.
