TCP Object

Updated: March 28, 2003

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

The TCP performance object consists of counters that measure the rates at which Transmission Control Protocol (TCP) segments are sent and received using 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, since the server was last started.

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, since the server was last started.

PERF_COUNTER_RAWCOUNT

Connections Established

Shows the number of TCP connections for which the state was either ESTABLISHED or CLOSE-WAIT, since the server was last started.

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, since the server was last started.

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, since the server was last started.

PERF_COUNTER_RAWCOUNT

Segments Received/sec

Shows the rate, in incidents per second, at which segments were received, including those received in error. This count includes segments received on currently established connections. Segments Received/sec is a subset of Segments/sec.

PERF_COUNTER_COUNTER

Segments Retransmitted/sec

Shows the rate, in incidents per second, at which segments containing one or more previously transmitted bytes were retransmitted.

PERF_COUNTER_COUNTER

Segments Sent/sec

Shows the rate, in incidents per second, at which segments were sent. This value includes those on current connections, but excludes those containing only retransmitted bytes. Segments Sent/sec is a subset of Segments/sec.

PERF_COUNTER_COUNTER

Segments/sec

Shows the rate, in incidents per second, at which TCP segments were sent or received using the TCP protocol. Segments/sec is the sum of the values of Segments Received/sec and Segments Sent/sec.
