I have an Ubuntu 12.04 server that I am troubleshooting, and I would like to use iotop. However, it seems that 12.04 doesn't have CONFIG_VM_EVENT_COUNTERS enabled by default (required by iotop).

I really want to avoid rebooting the machine. Is there any way to get it enabled without doing so?

Thanks, Tom

You might be able to use KSplice to do what you want here. At least assuming that a kernel for Ubuntu 12.04 exists with that configuration option enabled.

Interesting. I didn't think of this. I think it might work. Thanks! –  Tom Scrace Jun 28 '13 at 15:37
