Hi all,

Wondering if anyone knows of any tools I can run on my Dom0 to log various stats (like CPU usage, memory usage, etc) for each guest domain for analysis over a period of time? I can see that xentop displays that information anyway but would be nice to be able to present that information on a web based interface for day to day administration.

Also any tools that send out email notifications in case of a guest running in critical condition like out of memory etc.

Zenoss, Nagios, etc.

Also, if you care about performance and stability, don't run anything on dom0 that isn't directly related to keeping the domUs running (qemu, block device backends, xend, etc.)

I'm looking for the same thing. Looks like it's going to take some development work. I have found a interesting nagios plugin, see:

Have you looked to see if there are snmp MIBs for what you need? I know that works pretty well for monitoring per-DomU disk and network stats, I don't know if it would work for per-domU CPU (without running SNMP on the DomUs themselves, which I'd like to avoid.)
