NWLink SPX Object

The NWLink SPX performance object consists of counters that measure data transmission and session connections for computers using the SPX protocol.

Datagrams/sec

Datagrams/sec is the rate at which datagrams are processed by the computer. This counter displays the sum of datagrams sent and datagrams received. A datagram is a connectionless packet whose delivery to a remote is not guaranteed.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Datagram Bytes/sec

Datagram Bytes/sec is the rate at which datagram bytes are processed by the computer. This counter is the sum of datagram bytes that are sent as well as received. A datagram is a connectionless packet whose delivery to a remote is not guaranteed.

Detail Level: Advanced
Counter Type: PERF_COUNTER_BULK_COUNT

Packets/sec

Packets/sec is the rate at which packets are processed by the computer. This count is the sum of Packets Sent and Packets Received per second. This counter includes all packets processed: control as well as data packets.

Piggyback Ack Queued/sec

Piggyback Ack Queued/sec is the rate at which piggybacked acknowledgments are queued. Piggyback acknowledgments are acknowledgments to received packets that are to be included in the next outgoing packet to the remote computer.

Piggyback Ack Timeouts

Piggyback Ack Timeouts is the number of times that a piggyback acknowledgment could not be sent because there was no outgoing packet to the remote on which to piggyback. A piggyback ack is an acknowledgment to a received packet that is sent along in an outgoing data packet to the remote computer. If no outgoing packet is sent within the time-out period, then an ack packet is sent and this counter is incremented.
