Commit dd4e37b445da7f367746fb83d92e21b8dc3d8eb8 in kudu's branch
refs/heads/master from Alexey Serbin
[ https://gitbox.apache.org/repos/asf?p=kudu.git;h=dd4e37b44 ]
KUDU-3561 skip tablet entities in Prometheus format
Currently, the Prometheus metrics writer outputs only server-level
metrics. Prior to this patch, the Prometheus metrics writer would
output a warning message for every tablet it encounters while iterating
through all the existing metric entities.
This patch addresses the issue: the tablet entries are now silently
skipped, as they should.
I also added a TODO for KUDU-3563 to output tablet-level metrics
in Prometheus format as well.

> I encountered the same issue as KUDU-3549, so I recompiled Kudu using the
> master branch.
> Now Prometheus is able to collect metrics from Kudu correctly through the
> /metrics_prometheus endpoint.
> However, I noticed a large number of "Failed to write entity [xxx] as
> Prometheus: Not found: Entity is not relevant to Prometheus" warning logs in
> the Tserver's logs.

> Could you please confirm if this is a code issue? If not, how can I reduce
