No Disk Monitor Data

[msaundrs]

I installed (the free) version 3.0.2.105, and although the monitors for CPU, Memory, Networking and Swap display data, the DISK monitor does not display ANY data. The Disk field reads 'no data available'.

All disk related counters are enabled.

Could this be due to my virtual machines all residing on NFS storage?

msaundrs, yes - this is due to NFS storage. ESX hosts do not provide any performance counters for such storage.

OK, thanks you.
I'll look into using nfsstat or sar...
