The MSiSCSI_ConnectionStatistics structure is used by iSCSI initiators to report statistics for a connection within a session.
iSCSINameA wide character string that contains the name of the iSCSI target.
CIDThe iSCSI connection identifier (ID) for this connection instance. This ID is an internal value that the iSCSI protocol uses to identify the connection. Do not use this ID. Application software should use the connection identifier that the LoginToTarget and AddConnectionToSession methods return in the UniqueConnectionId parameter.
USIDThe iSCSI session ID for this connection instance. This ID is an internal value that the iSCSI protocol uses to identify the session. Application software should use the session identifier that the LoginToTarget and AddConnectionToSession methods return in the UniqueSessionId parameter.
UniqueAdapterIdA 64-bit integer that uniquely identifies an HBA initiator and a loaded instance of a storage miniport driver that manages the HBA. The initiator should use the address of the adapter extension or another address that the device driver owns to construct this ID. The initiator reports this value in the UniqueAdapterId member of the MSiSCSI_HBAInformation structure.
BytesSentThe number of bytes that are sent over this connection.
BytesReceivedThe number of bytes that are received over this connection.
PDUCommandsSentThe number of PDUs that are sent over this connection.
PDUResponsesReceivedThe number of PDUs that are received over this connection.
Initiators must register the MSiSCSI_ConnectionStatistics WMI Class with the following dynamic instance name for the connection:
targetname_#:#
The first number sign (#) is the value in the USID member of MSiSCSI_ConnectionStatistics, and the second number sign (#) is the value in the CID member. It is optional that you implement this class.
The totals tracked by this structure are valid for the lifetime of the connection in the session. Totals for all connections in a session are obtained in MSiSCSI_SessionStatistics structure.
