I use munin in a non-productive environment. It kind of works, but it create quite a heavy network load when the munin server asks for the data of the clients. Also, when the graphs are created, I experience "time went backwards" messages from my AMD 4050e, because it abrubtly awakes with quite a heavy load. But in principle it works, as I said. I also have create a litle plugin for load monitoring.

Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences.

We are using Munin for simple monitoring of system resources. I already reported one minor issue with iostat Munin plugin [1]. This is the only one issue we were experiencing with Munin. I will recommend you Ganglia [2] if you need more sophisticated monitoring tool. I am not sure about the support of Xen domU''s in Ganglia.

One important point to note is that the default Linux sar interval is an unhelpful ten minutes. A better default is five seconds, dropping to ine second to investigate erratic performance issues. This doesn''t cause a substantive IO hit but it does use a lot of disk space.
