Am going through the rather painful process of trying to monitor cassandra using Cacti (it's what we use at work). At the moment it feels like a losing battle :)
Does anyone know of some cacti resources for monitoring the JVM or Cassandra metrics other than... mysql-cacti-templates http://code.google.com/p/mysql-cacti-templates/ - provides templates and data sources that require ssh and can monitor JVM heap and a few things. Cassandra-cacti-m6 http://www.jointhegrid.com/cassandra/cassandra-cacti-m6.jsp Coded for version 0.6* , have made some changes to stop it looking for stats that no longer exist. Missing some metrics I think but it's probably the best bet so far. If I get it working I'll contribute it back to them. Most of the problems were probably down the how much effort it takes to setup cacti. jmxterm http://www.cyclopsgroup.org/projects/jmxterm/ Allows for command line access to JMX. I started down the path of writing a cacti data source to use this just to see how it worked. Looks like a lot of work. Thanks for any advice. Aaron
