Can't access Profiler tab

[fedecasanova72]

Describe the bug
I'm running locally my java application with java 21, using these VM options:

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.rmi.port=9010
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

I can attach the visualvm to the process, but there's no Profiler tab and the options in the menu related to the Profiler are disabled.

To Reproduce
It happens with any java application that I run, locally or remotely.
Somehow, I've seen it work recently once, but I cannot replicate it anymore, now it's always disabled...

Expected behavior
There should be a Profiler tab.

I can attach the visualvm to the process

How do you attach to the process?

It happens with any java application that I run, locally or remotely.

Note that profiler tab is available only for local processes running under same user as VisualVM.

[fedecasanova72]

I attach it through "Add JMX connection" (or if it appears directly for local processes, which not always work).

Oh, I didn't know that Profiler only works for local processes... I just tried now again and the tab appeared for local process... It's strange that sometimes does, and sometimes does not.

Is it impossible for remotely running processes? Not even with an agent installed or something?

Thank you.

I attach it through "Add JMX connection"

If you need to use JMX, it means that this is not the local process running under same user as VisualVM. Local processes are automatically detected and displayed next to VisualVM itself.

Oh, I didn't know that Profiler only works for local processes... I just tried now again and the tab appeared for local process... It's strange that sometimes does, and sometimes does not.

Automatically detected processes should have profiler tab. If not, this is something, which should be investigated. Can you narrow down the case, where it does not appears?

Is it impossible for remotely running processes? Not even with an agent installed or something?

Currently this is not supported by VisualVM - the usual workaround is to run VisualVM on remote machine and use vnc or rdp to display it locally.

I can't seem to calibrate the JVM. I'm using Amazon Corretto-17.0.13.11.1 (build 17.0.13+11-LTS) (Open JDK 17), we're on AWS. Is this an unsupported version or is there a workaround?

Amazon Corretto should work fine. Please file separate issue and provide more info.
