CentOS virt - Jan 2009 - Activity logger for Xen Guest Domains using libvirt

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.

Thanks.

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.)

not really virt-related your questions ;-)
munin for long-time monitoring and graphs. bigsister for critical limit 
monitoring and alerts.

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.)
