Subject [jira] [Resolved] (HBASE-4258) Metrics panel for the Off Heap Cache
Date Thu, 22 May 2014 00:06:38 GMT

     [ https://issues.apache.org/jira/browse/HBASE-4258?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack resolved HBASE-4258.

    Resolution: Won't Fix

Resolving as won't fix.  Adds metrics for slabcache exclusively.  We don't want this.  Instead
we want a generic means of doing metrics on block cache implementations. We have that (BlockCache
Interface) and the L1+L2 implementations (DoubleBlockCache, etc.) report currently by aggregating
L1 and L2 stats. We'll probably want to have them report separately going forward but not
in this cache-particular way.

> Currently, stats and configuration are handled by logs/an xml file, respectively. There
should be a better and more intuitive graphical interface for this.
> We could also add metrics to the RS metrics page.
