Subject Re: How to use JConsole to connect to a Cassandra cluster in Amazon EC2?
Date Thu, 03 Mar 2011 12:28:48 GMT
If you edit the $CASSANDRA_HOME/conf/ script, you should be
able to set up ssl for the JMX connection. That should allow you to do a
direct connection from a locally running JConsole to the JMX port on the
public IP of your EC2 instance.
