Hello, Instead of parsing the output from nodetool (running nodetool is quite intensive) maybe you could have a java program that would monitor via JMX (org.apache.cassandra.net.FailureDetector).
You have less burden compared to running periodically nodetool and more control on the things that you could do.

So, when I stop cassandra on a node for maintenance, all nodes stats emailing alarms. Any way to temporarily make the node under maintenance invisible from "nodetool status" output? Thanks
