Hi All,

I need to do maintenance work for a C* cluster with about 10 nodes. Pleas= e recommend a C* operation and maintenance tools you are using.
= I also noticed my C* deamon using large memory while doing nothing. Is the= re any convenent tool to deeply analysize the C* node memory?
Cheers,
Simon
