I have a server with two round-robin 4GB HBAs to a fiber switch and was wondering if I can measure activity/throughput on these HBAs using Perfmon? If so, which counters would I use? I initially thought Network, but perhaps I'd have to do something with PhysicalDisk.
PerfMon measures this with the
Physical disk performance object -> Avg. Disk sec/Transfer or
This accounts for the time spent on the following:
- Class Driver – manages the device type, such as disks, tapes, etc.
- Port Driver – manages the transport protocol, such as SCSI, FC, SATA, etc.
- Device Miniport Driver – This is the device driver for the Storage Adapter. It is supplied by the vendor of the device (Raid Controller, and FC HBA).
- Disk Subsystem – This includes everything below the Device Miniport Driver – This could be as simple as a cable connected to a single physical hard disk, or as complex as a Storage Area Network.
There's more information on TechNet that goes a bit deeper: Measuring Disk Latency with Windows Performance Monitor
