Agree - avoid parsing nodetool, if you can. I’d add that if anyone out there
is interested in JMX but doesn’t want to deal with Java, you should install
Jolokia so you can interact with Cassandra’s JMX data via a language
independent REST-like interface.

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
have found these
much more actionable than up/down alerts from a single node’s view of the whole
cluster (like nodetool status)

I don't think so.
I would use a different approach like for example only warn/email when the
node is down for 30 seconds or a minute depending on how long it takes for
your nodes to
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
