Sean Busbey updated HBASE-15134: -------------------------------- Component/s: regionserver metrics Compaction > Add visibility into Flush and Compaction queues > ----------------------------------------------- > > Key: HBASE-15134 > URL: https://issues.apache.org/jira/browse/HBASE-15134 > Project: HBase > Issue Type: New Feature > Components: Compaction, metrics, regionserver > Reporter: Elliott Clark > Assignee: Abhishek Singh Chouhan > Attachments: HBASE-15134.patch, HBASE-15134.patch > > > On busy spurts we can see regionservers start to see large queues for > compaction. It's really hard to tell if the server is queueing a lot of > compactions for the same region, lots of compactions for lots of regions, or > just falling behind. > For flushes much the same. There can be flushes in queue that aren't being > run because of delayed flushes. There's no way to know from the metrics how > many flushes are for each region, how many are delayed. Etc. > We should add either more metrics around this ( num per region, max per > region, min per region ) or add on a UI page that has the list of compactions > and flushes. > Or both. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
