[jira] [Commented] (YARN-1166) YARN 'appsFailed' metric should be of type 'counter'

    [ https://issues.apache.org/jira/browse/YARN-1166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13821933#comment-13821933 ] 

Jian He commented on YARN-1166:
-------------------------------

bq. The main problem is that QueueMetrics are being driven by RMAppAttempt transitions rather than RMApp transitions
This also turns out to be the cause of YARN-915

> Currently in YARN's queue metrics, the cumulative metric 'appsFailed' is of type 'guage' - which means the exact value will be reported. 
> All other cumulative queue metrics (AppsSubmitted, AppsCompleted, AppsKilled) are all of type 'counter' - meaning Ganglia will use slope to provide deltas between time-points.
> To be consistent, AppsFailed metric should also be of type 'counter'.
