Re: operation and maintenance tools
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 Best regards, Vladimir Yudovin, Winguzone - Hosted Cloud Cassandra Launch your cluster in minutes.

Thank you for the response. Now I have more confidence on using nodetool:-) From: Dikang Gu Date: 2016-11-08 14:52 To: cassandra Subject: Re: operation and maintenance tools 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. --Dikang.
