[Users] Monitoring instances

[Edward Konetzko]

Anyone have that they have setup to monitor instances?  I am looking for 
something that can give me metrics on cpu, disk (io,space), memory and 
network.  Ideally the script would be smart enough to get the limits of 
the vz along with the utilization values.  I have seen a few plugins for 
monitoring systems such as collectd but none of them gather all the 
information needed so I thought I would see if anyone here had what I 
was looking for.

Thanks
Edward
