Disk queue depth

[maciej_wos]

I'd like to monitor depth of the queue for SCSI drives/LUNs. Is there any way to do it? I can't find a way.

From the VMware ESX console, the storage unit can be traced through Host Adapter Level or the Vmhba Level:

Host adapter level: the host adapter driver provides the list of LUNs that are detected for each fibre-channel port. The directory /proc/scsi/

See the contents : e.g. cat /proc/vmware/scsi/vmhba0//4\:41, where 4 is the scsci id and 41 is the LUN Number.

Thanks dkaur,

I'll check it out. But what I'm writing at the moment uses VIM API and I was wondering if there's a way of getting all stats altogether from the API (queue depth is only one of few things I'm querying...)

This stat was omitted from the current version. It will be included in a future release of the SDK.
