Subject Re: JMX metrics for monitoring
Date Tue, 18 May 2010 04:33:24 GMT
There are many, but here's what I found useful so far:
Per CF you have:
- Recent read/write latency
- PendingTasks
- Read/Write count

Globally you have, for each of the stages
(e.g. org.apache.cassandra.concurrent:type=ROW-READ-STAGE):
- PendingTasks
- ActiveCount

... and as you go you'll find more
