Yeah I thought about doing something like that...however I wanted to kind of look over the last 3 to 6 months for example...in order to account for any periods of high IO over the long term.
I can also look at each vm and add up the max IO of each of them and come up with the total that way. Can you give me a brief explanation about how you are gathering the per vm stats? Maybe I can figure out what is wrong with the cacti setup? I have tried graphing all the hard drives (sda, sdb, etc) including dm-2 (/var/lib/vz) but they do not seem accurate at all.
