Centos + Tekkit + VisualVM

[Hellocreeper]

Hello everyone,

I'm looking for some advice for the VisualVM to connect to the craftbukkit.jar (I had help in the past with windows and it worked great)!.

Currently when I launch the VisualVM I can get a memory dump, but I cannot get it to connect to the CPU for thread reading; has anyone had any luck with this?

What does it say when you mouse over the CPU box that's grayed out?

Its grey, says I need to connect using JXM

We are running CentOS 6.3 and VisualVM . It works without any hitch. I will take a look at how i can help you out with this when i get home :)

Sounds like you are trying to login remotely then? If so, VNC is an option if you don't want to mess with JXM. I would check out TightVNC for an easy installation.

As far as using JXM, maybe greed can help you more there as I am more familiar with Ubuntu.

My Setup is this:

Dedicated server running CentOS.

I login remotely using VNC (I will try TightVNC tonight).

While I'm on the actual VNC machine I try to run VisualVM from the localhost.

The application launches perfectly except I have major Graphic issues (its blank until I click on stuff to update the screen) !! annoying.

Finally, I see the tekkit.jar (in my case its renamed to craftbukkit.jar)

I open the craftbukkit .jar and I see the Sample > CPU / Memory.

The Memory sample works, but the CPU says I need to log in to the JXM. (This requires me to do some remote logging in -- But I'm remote trying to launch visualvm on the localhost??). I'm not on a firewall so all ports should be open.

Wonder what I should do. I love VisualVM.. saves servers lag.

Yeah, I'm not sure why you're having JXM problems if you are already logging in remotely. JXM was required for me to even do a memory dump, which you can already do...

How do I setup the JXM? Thats worth a shot.

Do I put the startup params in the visualvm startup, or in the tekkit.jar startup?
