Use the data in the following table to help you understand TCP statistics.
Variable | Value |
---|---|
ActiveOpens | The number of times TCP connections make a direct transition to the SYN-SENT state from the CLOSED state. |
PassiveOpens | The number of times TCP connections make a direct transition to the SYN-RCVD state from the LISTEN state. |
AttemptFails | The number of times TCP connections make 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 make a direct transition to the LISTEN state from the SYN-RCVD state. |
EstabResets | The number of times TCP connections make a direct transition to the CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT state. |
CurrEstab | The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. |
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 octets. |
RetransSegs | The total number of segments retransmitted, that is, the number of TCP segments transmitted containing one or more previously transmitted octets. |
InErrs | The total number of segments received in error (for example, bad TCP checksums). |
OutRsts | The number of TCP segments sent containing the RST flag. |
HCInSegs | The number of segments received, including those received in error. This count includes segments received on currently established connections. This object is the 64-bit equivalent of InSegs. |
HCOutSegs | The number of segments sent, including those on current connections, but excluding those containing only retransmitted octets. This object is the 64-bit equivalent of OutSegs. |
