A call to our VMWare gurus...
a prospect asked me today about whether we would be able to monitor the % load of IOPS on their datastores.
According to the prospect, one reason he sees for poor performance of their VMs is that their datastores are on overload and cannot deliver the IOPS required.
The question is:
- can you imagine any way how we could provide metrics like that? (VMWare probe doesn't seem to offer that)
- if we cannot deliver % values (which is probably hard as we'd need to determine the maximum IOPS available for that which would probably require a stresstest???), is there any way we could deliver absolute values?
any hints/help highly appreciated!
