With SpecGrabber you're able to get to know the CPU of the system where your Minecraft server is being hosted.
Commands
Command description:

Please note: As I' unaware that some hosts might not allow this plugin due to you can execute commands within the java applet from the Minecraft server (Running commands as like in the "system shell/command prompt"). So please pay attention if your server gets suspended/terminated because your host doesn't allow it I'm not responsible for it and leaving a review behind due to your fault is pretty dumb.
I've only compiled the plugin with maven so the source is NOT modified.
You are also free to modify the code but you may not sell it.
I give credit to Dylan Hansch for creating the plugin and posting the source on GitHub
