Members
DataBytesSent
Type: ULONGULONG
Number of client data bytes sent out.
TotalBytesSent
Type: ULONGULONG
Total bytes sent, consisting of source path message (SPM), original data (ODATA) and repair data (RDATA) sequences.
NaksReceived
Type: ULONGULONG
Number of NAKs received.
NaksReceivedTooLate
Type: ULONGULONG
Number of NAKs received after the send window advanced beyond the NAK'ed sequence.
NumOutstandingNaks
Type: ULONGULONG
Number of NAKs for which responses have not been sent.
NumNaksAfterRData
Type: ULONGULONG
Number of NAKs after repair data (RDATA) sequences were sent for which responses have not been sent.
RepairPacketsSent
Type: ULONGULONG
Number of repair data (RDATA) packets sent.
BufferSpaceAvailable
Type: ULONGULONG
Number of partial messages dropped.
TrailingEdgeSeqId
Type: ULONGULONG
Oldest sequence identifier in the send window.
LeadingEdgeSeqId
Type: ULONGULONG
Newest sequence identifier in the send window.
RateKBitsPerSecOverall
Type: ULONGULONG
Internally calculated send rate from the beginning of the session, in kilobits per second.
RateKBitsPerSecLast
Type: ULONGULONG
Send rate for the period specified by INTERNAL_RATE_CALCULATION_FREQUENCY.
TotalODataPacketsSent
Type: ULONGULONG
Total original data (ODATA) packets sent.
