Web Service Object
The TCP performance object consists of counters that measure the rates at which TCP segments are sent and received using the Transmission Control Protocol (TCP). It includes counters that monitor the number of TCP connections in each TCP connection state.
Counter Name |
Description |
Counter Type |
---|---|---|
Connection Failures |
Shows the number of times that TCP connections have made a direct transition to the CLOSED state from the SYN-SENT or SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state. |
PERF_COUNTER_RAWCOUNT |
Connections Active |
Shows the number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state. |
PERF_COUNTER_RAWCOUNT |
Connections Established |
Shows the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. |
PERF_COUNTER_RAWCOUNT |
Connections Passive |
Shows the number of times that TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state. |
PERF_COUNTER_RAWCOUNT |
Connections Reset |
Shows the number of times that TCP connections have made a direct transition to the CLOSED state from either the ESTABLISHED or CLOSE-WAIT state. |
PERF_COUNTER_RAWCOUNT |
Segments/sec |
Shows the rate at which TCP segments are sent or received using the TCP protocol. Segments/sec is the sum of the values of TCP\ Segments Received/sec and TCP\Segments Sent/sec. |
PERF_COUNTER_COUNTER |
Segments Received/sec |
Shows the rate at which segments are received, including those received in error. This count includes segments received on currently established connections. Segments Received/sec is a subset of TCP: Segments/sec. |
PERF_COUNTER_COUNTER |
Segments Retransmitted/sec |
Shows the rate at which segments containing one or more previously transmitted bytes are retransmitted. |
PERF_COUNTER_COUNTER |
Segments Sent/sec |
Shows the rate at which segments are sent. This value includes those on current connections, but excludes those containing only retransmitted bytes. Segments Sent/sec is a subset of TCP\ Segments/sec. |
PERF_COUNTER_COUNTER |
