TCP Object

The TCP performance object consists of counters that measure the rates at which TCP Segments are sent and received by using the TCP protocol. It includes counters that monitor the number of TCP connections in each TCP connection state.

Segments/sec

Segments/sec is the rate at which TCP segments are sent or received using the TCP protocol.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Connections Established

Connections Established is the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Connections Active

Connections Active is the number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Connections Passive

Connections Passive is the number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Connection Failures

Connection Failures is the number of times TCP connections have made a direct transition to the CLOSED state from the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Connections Reset

Connections Reset is the number of times TCP connections have made a direct transition to the CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT state.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Segments Received/sec

Segments Received/sec is the rate at which segments are received, including those received in error. This count includes segments received on currently established connections.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Segments Sent/sec

Segments Sent/sec is the rate at which segments are sent, including those on current connections, but excluding those containing only retransmitted bytes.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Segments Retransmitted/sec

Segments Retransmitted/sec is the rate at which segments are retransmitted, that is, segments transmitted containing one or more previously transmitted bytes.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER
