Subject [jira] [Commented] (AMBARI-17133) Replace underscore character from Storm metrics sink
Date Thu, 09 Jun 2016 02:01:20 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-17133?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15321777#comment-15321777

Jungtaek Lim commented on AMBARI-17133:
---------------------------------------

Since patch is small and it's on top of AMBARI-16946, it would be better to address this from
AMBARI-16946 and mark as resolved once AMBARI-16946 will be resolved.

>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-metrics
>    Affects Versions: 2.4.0
>            Reporter: Jungtaek Lim
>
> 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.)
