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.
Namespace value is root/CIMV2.
WMI Provider value is WmiPerfInst.
A short textual description (one-line string) for the statistic or metric.
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.
Connections Active is the number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state. In other words, it shows a number of connections which are initiated by the local computer. The value is a cumulative total.
Connections Established is the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
Connections Passive is the number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state. In other words, it shows a number of connections to the local computer, which are initiated by remote computers. The value is a cumulative total.
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.
A textual description of the statistic or metric.
The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property.
Segments/sec is the rate at which TCP segments are sent or received using the TCP protocol.
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.
Segments Retransmitted/sec is the rate at which segments are retransmitted, that is, segments transmitted containing one or more previously transmitted bytes.
Segments Sent/sec is the rate at which segments are sent, including those on current connections, but excluding those containing only retransmitted bytes.
