Dear list,

as my Xen3 server is finaly becomming ready for production I was
wondering if anyone has written a xen usage monitoring/logging tool?

Something like xm top, but with continuose logging to a (rr)database.

Or a munin plugin?

I can't remember seeing anything simmilar on the list.

BTW: where does xm top get the NETTX(k) and NETRX(k) from?

For a munin plugin I'd imagin two modes:

- just monitor cpu usage off all domains (dom0 and domU) in one graph.
  This can be parsed from xm list, or as suggested 2004/12/xx using some
  more low level xen api. But I don't know how to figure out which of
  the real CPU was used, otoh this information might not be relevant at
  all.
- monitor just one domain. But all data, like xm top does.
