how to monitor io?

Is there anyway to monitor IO besides watching the ports on my switch?

Check the network statics from the GUI go to STATUS -> hardware -> Function: Server statistics then select Network. There you will have information on bits/s recieved and sent for each nic.

I remember I was able to get to some page with graphs before, but I don't remember how I got there. I just tried what you asked and I get a page that just says check_sys

After my NAS was having problems I rebooted open-e and this function is working again.
