Console command to check memory usage?

[AnrDaemon]

Is there a console command to see server memory usage?

The server is running in a Linux box, console only, no GUI.

How does that help seeing Java VM memory usage?

Useful answers, please.

If there's no other way around it…

I just see that Windows verion of the server do have its own memory usage counter.

But I'm failing to see, if the same information is availabe in console.

Do you want to see the memory usage of the Java VM? Then I already gave you the answer... Use the

top

command for example. It'll give you a table with all Processes currently running and their CPU / Memory usage (kinda like the Task Manager of Windows). You can sort it by memory usage with

M

. the

COMMAND

column has the process name in it.

Anything other than that, you'll need a Java profiler, unfortunately VisualVM doesn't run on console-only, so you'll need a different one... You can probably use HPROF, but I never used it personally, so I can't help you with that other than link to the official documentation.

@SanAndreasP, with all due respect, this is a Java modification to a Java application community forum.

I sincerely believe, that an average person visiting these parts of internet could add 2 to 2 and get the answer, that, indeed, I'm looking for memory usage of the application itself, not VM. As it is apparent that under Linux, VM always claim entire -Xmx region without a hesitation.

I'll take a look into that app you linked, thank you.
