Command Line Client for JMX

JMX is a mechanism where we can used to monitor and control our java applications remotely. We can expose variables and methods to outside using JMX.  To access these exposed variables or methods, we have to use JMX Client. JConsole is the JMX client application shipped with Java. It is a swing based application.

There is nothing wrong with JConsole if I'm using it in from my desktop. But issue is when I want to run it on a remote machine through ssh, I can't use X because of bandwidth limitations. So ideal tool for such situation is to use CLI tool.

After searching few minutes in goolgle I found this cute little tool called "Jmxterm (JMX  Terminal)". It is again a Java application and give you all the features you need when you use JMX. It is really user friendly as well. It has auto command completion and also can remember previous command you used. It is just like bash.

[sandarenu@localhost jmx-commandline]$ java -jar jmxterm-1.0-alpha-4-uber.jar
