SAN Fibre Channel (FC) Protocol metrics relate to a request coming in through an HBA port, being queued by priority, and eventually making its way to the software layers that service the request. The request is routed back through the HBA port and on to the SAN Host. User interface (UI) statistics are visible to users.
