JMX metrics for monitoring
Hi!
Which JMX metrics do you use for Cassandra monitoring ? Which values can
be used for alerts ?

Here are the basics I discuss in Riptano's training classes:

Just as an FYI, Evident ClearStone supports monitoring of Cassandra clusters
in enterprise and EC2 deployments.
Evident ClearStone supports various NoSQL products (including Cassandra) and
distributed caching technologies. The product supports the aggregation of
metrics (from JMX) across all the nodes in the cluster. We also monitor JVM
stats like CPU, heap, and GC. The user interface is an Adobe Flex
application. We have also include some of the nodetool operations within the
product to allow you to point an click on a node to run some of the nodetool
functions. There's many more features in the product such as alerting and
historical reporting.

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
