No, because in my case memory is the most demanded resource.
I use the standard SNMP data (already defined in cacti for example) for
network traffic => I get data per *physical* interface. I don't know how to
get network traffic per IP address by SNMP. Perhaps the only way to do that
is by exploiting data from /proc/virtual/<ctx>/cacct and using a similar
trick as I did (through some shell script).
The only difference in the how to would be on the "Getting vserver-stat
output" section :-) If you find it difficult and you are really interested, I
can spend some time on this.
I also use the standard SNMP data for load average on the host, not by vserver
(we could perhaps get this data using the "virt_load" flag on all vservers
and a shell script on the host). But this information doesn't seem very
relevant, just for cosmetic. Or would there be a real interest ?
