[jira] [Created] (HBASE-4214) Per-region request counters should be
clearer about scope
Per-region request counters should be clearer about scope
---------------------------------------------------------
Key: HBASE-4214
URL: https://issues.apache.org/jira/browse/HBASE-4214
Project: HBase
Issue Type: Bug
Components: metrics, regionserver
Affects Versions: 0.92.0
Reporter: Todd Lipcon
Fix For: 0.92.0
In testing trunk, I noticed that per-region request counters shown on table.jsp are lifetime-scoped, rather than per-second or some other time range. However, I'm pretty sure they reset when the region is moved. So, it's hard to use them to judge relative hotness of regions from the web UI without hooking it up to something lik OpenTSDB

--------------------------------------
This is true for a bunch of other counters as well.
Did we tackle this already with Metrics2?
