How to find How much RAM/CPU is used by a jail

[fahadshery]

Hi,

I have MySQL running in jail. I want to know how much RAM/CPU is used by it?
Is there an easier way to do that?

Cheers

Code:

iocage console <jailname>
top

This is great. Is there a way I could allocate more RAM to a jail?

This is symmetric multiprocessing, all jails running on the same kernel. The processes will get as much memory as they ask for.
You can limit the maximum amount a jail will use, check the iocage documentation for that.

Also you can do on the host:
top

Then press j to display the JID column, which corresponds to the number allocated to the jail which you can find with the jls command. Good for working out which jail is taking the CPU if you're not sure.
