_MSFC_FC4STATISTICS structure

Description

The MSFC_FC4STATISTICS structure is used in conjunction with the GetFC4Statistics WMI method to report traffic statistics on a port of type Nx_Port for the indicated FC-4 protocol.

Members

InputRequests

Indicates the number of input requests.

OutputRequests

Indicates the number of output requests.

ControlRequests

Indicates the number of control requests.

InputMegabytes

Indicates the number of megabytes of data that has been input.

OutputMegabytes

Indicates the number of megabytes of data that has been output.

Remarks

The statistics counters whose values are reported in the members of this structure are 64-bit signed integers that wrap to zero on exceeding 2**63-1. The statistics counters are not reset during normal operation, so traffic rates may be determined by the difference of counter values derived from two successive calls, with appropriate adjustments to for counter wrap.

If an HBA does not support a specific statistic, it shall return the value of -1 for corresponding counter.
