> Field | Description
> --- | ---
> AttemptFails | The number of times 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 TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
> InErrs | The total number of segments received in error (e.g., bad TCP checksums).
> ActiveOpens | The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.
> PassiveOpens | The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.
> EstabResets | 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.
> InSegs | The total number of segments received, including those received in error. This count includes segments received on currently established connections.
> OutSegs | The total number of segments sent, including those on current connections but excluding those containing only retransmitted bytes.
> RetransSegs | The total number of segments retransmitted - that is, the number of TCP segments transmitted containing one or more previously transmitted bytes.
> OutRsts | The number of TCP segments sent containing the RST flag.
