Syntax for using JMX term to connect to Cassandra

[Jan]

HI Folks; 
I am trying to use JMXterm,  a command line based tool to script & monitor C* 
cluster. Would anyone on this forum know the exact syntax to connect to 
Cassandra Domain using JMXterm  ?Please give me an example. 
I do 'not'   intend to use OpsCenter or any other UI based tool.
thanksJan
