JVM Monitoring

[keerthi.seetharaman]

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:

The documentation assumes the particular JVM you are trying to monitor has exposed JMX endpoints that the plugin can reach.

Thanks @mcapra!

Thios should get you going, let us know if you need something further

We tried it and its not working.

Please suggest what needs to be done.

We tried it and its not working.

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

As this is new request to monitor to JVM so please let us know what can be done to monitor the number of jvm process.

Let us know in case if any more details are required.

It was mentioned earlier we have documentation on this

There's official documentation for using check_jmx to remotely monitor JVMs:

To which you replied

We tried it and its not working.

So to answer your question

Let us know in case if any more details are required.

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

[scottwilkerson]

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)
