MsgHeader (24 bytes): This field MUST contain a MESSAGE_PACKET structure (as specified in [MS-DTCO] section 2.2.4.1). The dwUserMsgType field MUST be 0x00003001. The dwcbVarLenData field MUST be 84 plus the size in bytes of the timeTransactionsUp field.
cOpen (4 bytes): A 4-byte unsigned integer indicating the number of currently opened transactions.
cCommitted (4 bytes): A 4-byte unsigned integer indicating the current number of committed transactions.
cAborted (4 bytes): A 4-byte unsigned integer indicating the current number of aborted transactions.
cInDoubt (4 bytes): A 4-byte unsigned integer indicating the current number of in-doubt transactions.
cHeuristic (4 bytes): A 4-byte reserved field that MUST be set to 0x00000000.
cOpenMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cOpen field since the transaction manager was started.
cCommittedMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cCommitted field since the transaction manager was started.
cAbortedMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cAborted field since the transaction manager was started.
cInDoubtMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cInDoubt field since the transaction manager was started.
cHeuristicMax (4 bytes): A 4-byte reserved field that MUST be set to 0x00000000.
cForcedCommit (4 bytes): A 4-byte unsigned integer indicating the current number of transactions that were in doubt, and were forced to commit.
cForcedAbort (4 bytes): A 4-byte unsigned integer indicating the current number of transactions that were in doubt, and were forced to abort.
cAvgResponseTime (4 bytes): A 4-byte unsigned integer indicating the current average time in milliseconds for transaction committing.
cMinResponseTime (4 bytes): A 4-byte unsigned integer indicating the current minimum time in milliseconds for transaction committing.
cMaxResponseTime (4 bytes): A 4-byte unsigned integer indicating the current maximum time in milliseconds for transaction committing.
timeTransactionsUp (4 bytes): This field SHOULD contain either an unsigned 4-byte integer, or 4 bytes of padding (containing non-deterministic values) followed by an 8-byte unsigned integer in 64-bit Windows, that specifies the number of seconds that elapsed from a baseline time to when the service was started.<2> In the Windows implementation, the Management Client Role does not use this field. To distinguish between 32-bit and 64-bit Windows, the implementation can check the dwcbVarLenData field, which varies based on 32-bit and 64-bit implementations. The baseline time used for this field MUST be midnight January 1, 1970, Coordinated Universal Time (UTC).
systemTimeTransactionsUp (16 bytes): A SYSTEMTIME structure (as specified in [MS-DTYP] section 2.3.13) indicating the time when the service was started.
dwTimeStamp (4 bytes): A 4-byte unsigned reserved field that MUST be set to 0x00000000.
cSinglePhaseInDoubt (4 bytes): A 4-byte unsigned integer indicating the current number of transactions that have entered the single-phase in-doubt state.
