T tincboy Renowned Member Apr 13, 2010 466 6 83 Oct 5, 2011 #5 Thanks for your kind response, Would you please guide me a little bit more? What do you mean by store time series? Do you query save VM's total read/write on a fixed period and save them in db?

Please read the documentation at http://oss.oetiker.ch/rrdtool/ Basically I store total read/write with a timestamp, the rest is done by the rrdtool.
