I am in the midst of instrumenting cassandra server using AppMOn v6.5.5 but would require a b it more details on instrumenting Cassandra Server. I will use the extract a snapshot of 6.5 doc to state my request for more info with [chuan>>] tag.
"To trace Cassandra calls from client to server, add a new Agent Group for the Cassandra server node. Make sure that this Agent Group has the Cassandra Sensor placed. As Cassandra does a lot of threading, you may want to disable the Thread Activation Sensor to reduce the amount of data collected. However, in order to be able to see Cassandra CQL3 protocol based statement execution, the Executor Tagging sensor needs to be active. [Chuan]>> "I read that I would require to install the dtagent to cassandra server, right ?"
Then add the AppMon Agent parameter to the JVM_OPTS in the Cassandra server configuration file and restart your nodes" [Chuan]>> "what's the configuration string to be added to JVM_OPTS ? or should I add it in cassandra start up script ?"
