Hi all, I need to monitor performance of my xen hosts. I want to know when i''m hitting memory I/O, disk I/O, CPU resource limits or any other resource. Ideally, I would be monitoring this via SNMP, however it would appear that when I monitor CPU usage of dom0 via SNMP, the stats I see are for just dom0, not the entire xen host. I''ve noticed there''s a tool called ''xenmon'', but I have yet to install it - I though I''d ask how you guys monitor your xen servers before I did. Kind regards, -- Ian P.

Using these would require of course either a webserver on your dom0, or another machine to collect the munin stats and to build the graphs.

Basically from there it checks for CPU usage and Network traffic. I don''t know if it is possible to check active memory bandwidth usage, could be interesting, but it would mean Xen needs to aggregate it to be useful later, otherwise it would cost a lot of resources checking everything every second.
