Re: nodetool status and node maintenance


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.

I have script that parses "nodetool status" output and emails alerts if any node is down. 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
