Can someone please verify the correct method for calculating IOPS with VirtualCenter 2.5. If I understood this post correctly, then IOPS can be calculated by dividing "Disk Read Requests" and "Disk Write Requests" by the data sample rate.
In my attachment the data sample rate was 120 seconds. So does this mean that the average IOPS in the attached example is 2.97 (3.65 + 352.58 / 120 seconds)?

The report sample (IOPS.PNG) was not from "Realtime" data, it was older data. Therefore, if I understand this correctly, the sample rate should equate to the relevant Statistics value set in "Advanced\VirtualCenter Management Server Configuration\Statistics", which in our case is 2 minutes (or 120 seconds). Is that correct?
