MSiSCSI_ConnectionStatistics structure (iscsiprf.h)
The MSiSCSI_ConnectionStatistics structure is used by iSCSI initiators to report statistics for a connection within a session.
Syntax
typedef struct _MSiSCSI_ConnectionStatistics {
WCHAR iSCSIName[223 + 1];
USHORT CID;
ULONGLONG USID;
ULONGLONG UniqueAdapterId;
ULONGLONG BytesSent;
ULONGLONG BytesReceived;
ULONGLONG PDUCommandsSent;
ULONGLONG PDUResponsesReceived;
} MSiSCSI_ConnectionStatistics, *PMSiSCSI_ConnectionStatistics;
Members
iSCSIName[223 + 1]
A wide character string that contains the name of the iSCSI target.
CID
The 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.
USID
The 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.
UniqueAdapterId
A 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.
BytesSent
The number of bytes that are sent over this connection.
BytesReceived
The number of bytes that are received over this connection.
PDUCommandsSent
The number of PDUs that are sent over this connection.
PDUResponsesReceived
The number of PDUs that are received over this connection.
Remarks
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.
