Subject Re: Cassandra Monitoring
Date Sun, 19 Dec 2010 15:40:52 GMT
Another option is Evident ClearStone (
http://www.evidentsoftware.com/products/clearstone-for-cassandra/).

It collects the Cassandra metrics via JMX as well. As long as one node in
the cluster is configured, it'll find the rest of them. The UI is written in
Adobe Flex. The Cassandra management pack comes with some pre-built
visualizations for Cassandra. However, you can easily create adhoc
visualizations to monitor any other metric. Users can set thresholds and
alerts on JVM heap, GC, LiveSSTables, disk usage, cache hit rate,
compactions, CPU utilization, and other metrics. In addition, some of the
nodetool features have been incorporated into the UI for quick and simple
access.

In our upcoming Q1 release, we're adding support for system level monitoring
(via SAR) for the purposes of correlating application performance with
system.

Check it out on our website.
