Jayush Luniya reopened AMBARI-17133:
------------------------------------
> Replace underscore character from Storm metrics sink
> ----------------------------------------------------
>
> Key: AMBARI-17133
> URL: https://issues.apache.org/jira/browse/AMBARI-17133
> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics
> Affects Versions: 2.4.0
> Reporter: Jungtaek Lim
> Fix For: 2.4.0
>
>
> Since Ambari Metric Service uses "._" as separator for splitting metric and
> functions, metric name shouldn't contain "._".
> Storm built-in metrics have metric names starting on '__' and with
> AMBARI-16946 metric name is placed after '.' which finally makes '._' which
> makes parsing messed up.
> We should remove '_' characters from metric name or replace them with '-' or
> alike.
> (Replacing is more safer way if we replace them with special character.)
