Subject [jira] [Updated] (AMBARI-17445) Storm metrics sink: expand metrics name to contain additional informations
Date Mon, 27 Jun 2016 03:25:52 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-17445?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.)

> 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.
