Consider a different approach, Performance Co-Pilot will provide a machines metrics in a unified format. I use a bash script and grep | sed out what I want and call gmetric. One nic or 6, I get the in and out stats on all. Also nice because I get per-partition io stats. Current version of pcp is 2.7.1.1
