TCP Connection Statistics - G2

Description

Monitors the TCP connection statistics like tcp active opens, tcp passive opens, tcp failure attempts, tcp establish resets and tcp current establishments. Can be applied on devices to check the TCP connection statistics.

Supported Metric

Monitor NameMetric NameMetric Display NameUnitDescription
TCP Statisticstcp.active.opensTCP Active OpensThe number of times that TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.
tcp.attempt.failsTCP Attempt FailsThe number of times that TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times that TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
tcp.current.established.connTCP Current Established ConnectionsThe number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
tcp.established.resetsTCP Established ResetsThe number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
tcp.passive.opensTCP Passive OpensThe number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.
tcp.errors.inTCP Errors InpsecThe total number of segments received in error (e.g., bad TCP checksums).
tcp.segments.inTCP Segments InpsecThe total number of segments received, including those received in error. This count includes segments received on currently established connections.
tcp.segments.retransTCP Retransmitted SegmentsThe delta of segments retransmitted; that is, the delta of TCP segments transmitted containing one or more previously transmitted octets.
