["Riley Patterson (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-4057?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Riley Patterson updated HBASE-4057:
-----------------------------------

    Attachment: HBASE-4057.patch

Includes extended TaskMonitor with consideration for high-frequency, short duration changes, a new MonitoredRPCHandler class, integration with the RPC, and filtered exposure both as and HTML table and as JSON via jamon.

Will also put this on the review board, as it's a rather large patch.

> One of the features that our DBAs use for MySQL analysis is "show processlist", which gives application-level stats about the RPC threads.  Right now, we use jstack but that is very core-developer-centric.  We need to create a similar tool that DBA/Ops/AppDevs can use.
