Jungtaek Lim updated AMBARI-17445:
----------------------------------
Attachment: AMBARI-17445-changes.png
Attaching the screenshot of output of metrics metadata.
We can see that metric name now contains topology name, component name, worker
host, worker port, task id, origin metric name.
If we want to make '.'(dot) aware metric name, we can also escape worker host
to replace '.' to '-' or another character.
(I left it as is because we can use wildcard '%' to match to multiple '.'
separated metric parts.)
> Storm metrics sink: expand metrics name to contain additional informations

> With AMBARI-16946 we expanded metric name to have component name, task id,
> and key when type of metric value is Map. Topology name was placed to appId.
> While talking with [~prajwal] and [~harsha_ch], we found that we should move
> out all necessary informations like topology name, worker host, worker port
> to metric name so that they can be templatized.
> This also supercedes AMBARI-17249 since all metrics will include worker host
> and worker port to metric name.
