There was a recent performance inefficiency in nodetool status with virtual nodes that will be fixed in the next releases (CASSANDRA-7238), so it should be faster with this fixed.
You can also query StorageServiceMBean.getLiveNodes() via JMX (jolokia or some other jmx client). For a list of useful management/status methods via JMX see https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/StorageServiceMBean.java . 2016-02-12 15:12 GMT-03:00 Kevin Burton <bur...@spinn3r.com>: > Is there a faster way to get the output of 'nodetool status' ? > > I want us to more aggressively monitor for 'nodetool status' and boxes > being DN... > > I was thinking something like jolokia and REST but I'm not sure if there > are variables exported by jolokia for nodetool status. > > Thoughts? > > -- > > We’re hiring if you know of any awesome Java Devops or Linux Operations > Engineers! > > Founder/CEO Spinn3r.com > Location: *San Francisco, CA* > blog: http://burtonator.wordpress.com > … or check out my Google+ profile > <https://plus.google.com/102718274791889610666/posts> > >
