Disk IOPS metrics in reports

I need disk iops in my reports. In default report disk performance usage is counted in Kb/s and so on. How to coclect disk iops per VM?

Many thanks in advice,


I know this is 2 years old but…

The IOPS is collected but not shown.
Instead the disk_usage_rate_average is used.

Do you know where IOPS are stored? Which metric?
