Re: [Xen-users] xen usage monitoring (munin plugin)

Thanks for the update on xenstats. xenupdate.py runs fine and creates the rrd files. However when running xengraph.py, it gives the following error:

Its complaining about --unit. Any help would be appreciated.

There is this for CPU time -> rrd
http://skaya.enix.org/wiki/XenStats

I needed to change a tiny something to get it working in Xen3:

diff xenupdate.py modified.xenupdate.py
16c16
<     name,id,mem,cpu,state,cputime,console=re.split ("[\t ]+",domain)
---
