JConsole location in Linux

jconsole is part of the Java SDK, it appears you only have the JRE installed.

You can run jconsole directly from your terminal by running the command jconsole.

reena@IM-1500:~$ jconsole

It will launch java monitoring console dialog.

From https://serverfault.com/questions/179908/fedora-jconsole-location:

Try running: yum provides */jconsole

that will tell you what package you need as well as where it's located in the package.
