NWLink SPX Object
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
The NWLink SPX performance object consists of counters that measure data transmission and session connections for computers that use the Sequenced Packet Exchange (SPX) protocol. This object reports valid data only for counters that monitor datagrams and packets; for frame-related counters, the object tends to report zero values.
| Counter Name | Description | Counter Type |
|---|---|---|
Bytes Total/sec |
Shows the total rate of bytes sent to or received from the network by the protocol, but shows only the bytes in frames that carry data. This is the sum of the values of Frame Bytes/sec and Datagram Bytes/sec. |
|
Connection Session Timeouts |
Shows the number of connections that are dropped because a session times out. This number is cumulative and shows a running total. |
|
Connections Canceled |
Shows the number of connections that are canceled. This number is cumulative and shows a running total. |
|
Connections No Retries |
Shows the number of connections that are successfully made on the first try. This number is cumulative and shows a running total. |
|
Connections Open |
Shows the number of connections currently open for this protocol. This counter shows the current count only and is not cumulative. |
|
Connections With Retries |
Shows the number of connections that are made after attempting to reconnect. A retry occurs when the first connection attempt fails. This number is cumulative and shows a running total. |
|
Datagram Bytes Received/sec |
Shows the rate at which datagram bytes are received by the computer. |
|
Datagram Bytes Sent/sec |
Shows the rate at which datagram bytes are sent from the computer. |
|
Datagram Bytes/sec |
Shows the rate at which datagram bytes are processed by the computer. This counter is the sum of the values of Datagram Bytes Received/sec and Datagram Bytes Sent/sec. |
|
Datagrams Received/sec |
Shows the rate at which datagrams are received by the computer. |
|
Datagrams Sent/sec |
Shows the rate at which datagrams are sent from the computer. |
|
Datagrams/sec |
Shows the rate at which datagrams are processed by the computer. This counter is the sum of the values of Datagrams Received/sec and Datagrams Sent/sec. |
|
Disconnects Local |
Shows the number of session disconnections that are initiated by the local computer. This number is cumulative and shows a running total. |
|
Disconnects Remote |
Shows the number of session disconnections that are initiated by the remote computer. This number is cumulative and shows a running total. |
|
Expirations Ack |
Shows the number of T2 timer expirations |
|
Expirations Response |
Shows the number of T1 timer expirations. |
|
Failures Adapter |
Shows the number of connections that are dropped because an adapter fails. This number is cumulative and shows a running total. |
|
Failures Link |
Shows the number of connections that are dropped due to a link failure. This number is cumulative and shows a running total. |
|
Failures No Listen |
Shows the number of connections that are rejected because the remote computer is not listening for connection requests. |
|
Failures Not Found |
Shows the number of connection attempts that fail because the remote computer cannot be found. This number is cumulative and shows a running total. |
|
Failures Resource Local |
Shows the number of connections that fail because of resource problems or shortages on the local computer. This number is cumulative and shows a running total. |
|
Failures Resource Remote |
Shows the number of connections that fail because of resource problems or shortages on the remote computer. This number is cumulative and shows a running total. |
|
Frame Bytes Received/sec |
Shows the rate at which data bytes are received by the computer. This counter shows only the bytes in frames that carry data. |
|
Frame Bytes Rejected/sec |
Shows the rate at which data bytes are rejected by the computer. This counter shows only the bytes in frames that carry data. |
|
Frame Bytes Re-Sent/sec |
Shows the rate at which data bytes are re-sent by the computer. This counter shows only the bytes in frames that carry data. |
|
Frame Bytes Sent/sec |
Shows the rate at which data bytes are sent by the computer. This counter shows only the bytes in frames that carry data. |
|
Frame Bytes/sec |
Shows the rate at which data bytes are processed by the computer. This counter is the sum of the values of Frame Bytes Received/sec and Frame Bytes Sent/sec. This counter shows only the bytes in frames that carry data. |
|
Frames Received/sec |
Shows the rate at which data frames are received by the computer. This counter shows only the frames that carry data. |
|
Frames Rejected/sec |
Shows the rate at which data frames are rejected by the computer. This counter shows only the frames that carry data. |
|
Frames Re-Sent/sec |
Shows the rate at which data frames are re-sent by the computer. This counter shows only the frames that carry data. |
|
Frames Sent/sec |
Shows the rate at which data frames are sent by the computer. This counter shows only the frames that carry data. |
|
Frames/sec |
Shows the rate at which data frames are processed by the computer. This counter is the sum of the values of Frames Received/sec and Frames Sent/sec. This counter shows only the frames that carry data. |
|
Packets Received/sec |
Shows the rate at which packets are received by the computer. This counter shows all packets processed (control as well as data packets). |
|
Packets Sent/sec |
Shows the rate at which packets are sent by the computer. This counter shows all packets sent by the computer (control as well as data packets). |
|
Packets/sec |
Shows the rate at which packets are processed by the computer. This counter is the sum of the values of Packets Sent/Sec and Packets Received/Sec. This counter includes all packets processed (control as well as data packets). NWLink SPX\Packets/sec is visible in IPX and NetBIOS. |
|
Piggyback Ack Queued/sec |
Shows the rate at which "piggybacked" acknowledgments, acknowledgements that are added by the receiver onto the next outgoing data frame, are queued. |
|
Piggyback Ack Timeouts |
Shows the number of times that a "piggybacked" acknowledgment, an acknowledgement that is added by the receiver onto the next outgoing data frame, cannot be sent because there is no outgoing frame. If no outgoing frame is sent within the time-out period, an acknowledgment frame is sent, and this counter is incremented. |
|
Window Send Average |
Shows the running average number of data bytes that are sent before waiting for an acknowledgment from the remote computer. |
|
Window Send Maximum |
Shows the maximum number of data bytes that are sent before waiting for an acknowledgment from the remote computer. |
