Lars Volker resolved IMPALA-6541.
---------------------------------
Resolution: Won't Fix
Fix Version/s: Not Applicable
There's doesn't seem to be any value in this. We are not aware of any tooling
that would scrape histograms and display them in a useful way, in particular
because Impala's native histograms can be reset from the /rpcz debug webpage.
> Add missing KRPC histograms to /metrics page

> Fix For: Not Applicable

> IMPALA-6269 left out the KRPC histograms from adding them to the /metrics
> page. We should consider adding them there. For the histograms coming from
> the KRPC code itself (using Kudu's metric classes) this will require wrapping
> them so that they can be registered in our metric groups.
