Hello Team,
Good Day.
We have requirement where we need to monitor running java process. Currently we have a plugin check_java.
So please let me know how to monitor for the same.
Let me know in case if any more details are required.
Regards,
Keerthi Prashanth S.

Is
check_java producing some sort of error messages or otherwise not working?
There's official documentation for using check_jmx to remotely monitor JVMs:
https://assets.nagios.com/downloads/nag ... ios-XI.pdf
The documentation assumes the particular JVM you are trying to monitor has exposed JMX endpoints that the plugin can reach.

What is "it"? Did you try check_java or check_jmx?
Can you share any specific errors you're encountering when using either plugin? Those error messages are vital in figuring out the solution.

@keerthi.seetharaman we need to know what error you are having with the doc to be of assistance. What is happening (we need more information than "its not working")?
Thanks

So to answer your question

The answer is Yes, we need to know if you actually followed that documentation?
And if so, what isn't working?

But this is java virtual machine..
How come JMX is as similar to JVM

JMX == Java Management Extensions
The only real way to get information out of java is through JMX, unless you are writing something else into your java application.
Other than this, you are only going to be able to do process checking (e.g. is java running)
