Enis Soztutar commented on HBASE-6025:
--------------------------------------
bq. You saying that what comes out of jmx will show in a hadoop webapp servlet
mounted at /jmx?
Yes, it comes from the Hadoop HttpServer class, which adds JMXJsonServlet to
serve for /jmx. That servlet finds all registered MBeans (including metrics)
and exports them via json.
bq. we ship 1.0.0 even in 0.94 which needs to be fixed
hadoop-1.0.3 is recently released with fixes for non-oracle jvms and other bug
fixes. We can switch to that.
bq. We should add a 'metrics' link along the top beside the log level, thread
dump, etc. servlets
Agreed. I learned about this from the Hadoop folks. We should make it more
visible.
bq. Oh, it looks like the jmx per-region stuff is showing under /jmx because
Elliott already added this to 0.94 and trunk
In my near-trunk test, I saw the dynamic metrics json, but nothing reported
underneath (did not spend much time on it). If it works for you, than what you
outlined seems like a good plan.
