Expand description

The IP agnostic version of TcpCounters.

Fields§

§invalid_ip_addrs_received: Counter

Count of received IP packets that were dropped because they had unexpected IP addresses (either src or dst).

§invalid_segments_received: Counter

Count of received TCP segments that were dropped because they could not be parsed.

§valid_segments_received: Counter

Count of received TCP segments that were valid.

§received_segments_dispatched: Counter

Count of received TCP segments that were successfully dispatched to a socket.

§received_segments_no_dispatch: Counter

Count of received TCP segments that were not associated with any existing sockets.

§listener_queue_overflow: Counter

Count of received TCP segments that were dropped because the listener queue was full.

§segment_send_errors: Counter

Count of TCP segments that failed to send.

§segments_sent: Counter

Count of TCP segments that were sent.

§passive_open_no_route_errors: Counter

Count of passive open attempts that failed because the stack doesn’t have route to the peer.

§passive_connection_openings: Counter

Count of passive connections that have been opened.

§active_open_no_route_errors: Counter

Count of active open attempts that have failed because the stack doesn’t have a route to the peer.

§active_connection_openings: Counter

Count of active connections that have been opened.

§failed_connection_attempts: Counter

Count of all failed connection attempts, including both passive and active opens.

§failed_port_reservations: Counter

Count of port reservation attempts that failed.

§checksum_errors: Counter

Count of received segments whose checksums were invalid.

§resets_received: Counter

Count of received segments with the RST flag set.

§resets_sent: Counter

Count of sent segments with the RST flag set.

§syns_received: Counter

Count of received segments with the SYN flag set.

§syns_sent: Counter

Count of sent segments with the SYN flag set.

§fins_received: Counter

Count of received segments with the FIN flag set.

§fins_sent: Counter

Count of sent segments with the FIN flag set.

§timeouts: Counter

Count of retransmission timeouts.

§retransmits: Counter

Count of retransmissions of segments.

§slow_start_retransmits: Counter

Count of retransmissions of segments while in slow start.

§fast_retransmits: Counter

Count of retransmissions of segments while in fast recovery.

§fast_recovery: Counter

Count of times fast recovery was initiated to recover from packet loss.

§established_closed: Counter

Count of times an established TCP connection transitioned to CLOSED.

§established_resets: Counter

Count of times an established TCP connection transitioned to CLOSED due to a RST segment.

§established_timedout: Counter

Count of times an established TCP connection transitioned to CLOSED due to a timeout (e.g. a keep-alive or retransmit timeout).
