After reading the VMware ESX 4.0 Update 2 Release Notes, and especially the What’s New, I was happy to discover that at least ESXTOP/RESXTOP now allow you to get performance counters for NFS datastores. ESX was missing this feature like the deserts miss the rain 🙂
Enhancement of the esxtop/resxtop utility— vSphere 4.0 Update 2 includes an enhancement of the performance monitoring utilities, esxtop and resxtop. The esxtop/resxtop utilities now provide visibility into the performance of NFS datastores in that they display the following statistics for NFS datastores: Reads/s, writes/s, MBreads/s, MBwrtn/s, cmds/s, GAVG/s(guest latency).
I’m also surprised that the other third party virtualization software vendors never came up with a solution to circumvent VMware’s (R)ESXTOP lack of visibility into performances of NFS datastores… Never, you sure? Stay tuned for more about that!
I’ll upgrade my home lab tonight and will do some tests… Damn it’s 8 hours away, I won’t be able to wait so long 🙂
