Subject Re: jmxterm "#NullPointerException: No such PID "
Date Tue, 18 Sep 2018 12:00:38 GMT
Further info:

I would expect to see the following when I list the jvm's:

Welcome to JMX terminal. Type "help" for available commands.
$>jvms
*25815    (m) - org.apache.cassandra.service.CassandraDaemon*
17628    ( ) - jmxterm-1.0-alpha-4-uber.jar

But jmxtem is not picking up the JVM for Cassandra for some reason.

Can someone point me in the right direction?  Is there settings in the
cassandra-env.sh file I need to amend to get jmxterm to find the cass jvm?

Im not finding much about it on google.

Thanks,
Phil
