"highest disk latency " on the performance tab not displaying

[cajx]

Is it normal to have absolutely no activity on the Highest Desk Latency portion of the default "1 day summary" on the performance tab in vCenter? I have the latest updates on vCenter and running ESXi 4.0.0 on my hosts. All hosts show CPU, Disk Usage, and Memory Usage... but zip on that disk latency. We are using a copule of IBM Nseries 6040 boxes I believe (same as Netapp 3040) with NFS (no fiber channel).

since NFS is network-based filesystem and not a block filesystem, you do not get disk performance stats for it, so it's normal.
