For memory usage you can use small command line tool 
https://github.com/patric-r/jvmtop

Also there are number of GUI tools that connect to JMX port, like jvisualvm

Hi All,



I need to do maintenance work for a C* cluster with about 10 nodes. Please 
recommend a C* operation and maintenance tools you are using.

I also noticed my C* deamon using large memory while doing nothing. Is there 
any convenent tool to deeply analysize the C* node memory?



Cheers,

Simon

Thank you for the response. Now I have more confidence on using nodetool:-)

Hi Simon, 

For a 10 nodes cluster, Cassandra nodetool should be enough for most C* 
operations and maintenance, unless you have some special requirements.

For the memory, you can check what's your JVM settings, and the gc log for JVM 
usage.
