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. General statistics contain any detailed statistics that a component collects which cannot be classified as error statistics or user statistics.
