We are seeing some latency at our application during testing.
We also see that it is due to load on one of the datastores (high queue depths for this LUN from the SAN).
We have a large number of VMs on this DS.
Is there a method by which we can determine which VM(s) are producing load (other than going through each one one-by-one)?
Something like a nice GUI which shows read/write IOPS/throughput graphs for each VM in a particular datastore?
I'm fairly certain that the hardware is performing as expected.
I also know we can improve performance by adding resource (adding disks to this LUN, etc.), however, I'm trying to determine exactly where the load is coming from and then if the load is justified.
TIA,
Rich
