This object tracks the number of SCSI commands this specific authorized remote initiator has sent to this specific local target device or port, scoped to that one initiator-target relationship rather than the target's aggregate traffic. An admin troubleshooting one particular host's storage performance issue on a shared array isolates this initiator-target pairing's command count to see that host's individual command rate without the noise of every other host sharing the same target. Comparing this figure against the target's aggregate command counter lets the admin calculate what fraction of the target's overall load one specific host actually represents.
