MSiSCSI_SessionStatistics structure (iscsiprf.h)

The MSiSCSI_SessionStatistics structure is used by iSCSI initiators to report session statistics.

Syntax

typedef struct _MSiSCSI_SessionStatistics {
  WCHAR     iSCSIName[223 + 1];
  ULONGLONG USID;
  ULONGLONG UniqueAdapterId;
  ULONGLONG BytesSent;
  ULONGLONG BytesReceived;
  ULONGLONG PDUCommandsSent;
  ULONGLONG PDUResponsesReceived;
  ULONGLONG DigestErrors;
  ULONGLONG ConnectionTimeoutErrors;
  ULONGLONG FormatErrors;
} MSiSCSI_SessionStatistics, *PMSiSCSI_SessionStatistics;

Members

iSCSIName[223 + 1]

A wide character string that contains the name of an iSCSI target.

USID

The iSCSI session identifier (ID) for this connection instance. This ID is an internal value that the iSCSI protocol uses to identify the session. Do not use this ID. 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 session.

BytesReceived

The number of bytes that are received over this session.

PDUCommandsSent

The number of PDUs that are sent over this session.

PDUResponsesReceived

The number of PDUs that are received over this session.

DigestErrors

The number of digest errors that have occurred in this session.

ConnectionTimeoutErrors

The number of connection time-out errors that have occurred in this session.

FormatErrors

The number of format errors that have occurred in this session.

Remarks

It is optional that you implement this class.
