TCP Version 6 Overview (PI_TCP6)
Function
The TCP Version 6 Overview (PI_TCP6) record stores the performance data per unit time on the number of times TCP segments were sent/received when the TCP protocol of Internet Protocol Version 6 was used, and the number of TCP connections.

---|---|---|---|---|---|---|
Conn Failures (CONNECTION_FAILURES) | Combined total of the number of times the TCP connection state transitioned directly from SYN-SENT or SYN-RCVD to CLOSED, and the number of times the TCP connection state transitioned directly from SYN-RCVD to LISTEN following the OS startup.# | AVG | ulong | No | -- | -- |
Conns Active (CONNECTIONS_ACTIVE) | Number of times the TCP connection state transitioned directly from CLOSED to SYN-SENT following the OS startup# | AVG | ulong | No | -- | -- |
Conns Established (CONNECTIONS_ESTABLISHED) | Total number of TCP connections that were either in the ESTABLISHED or CLOSE-WAIT state# | AVG | ulong | No | -- | -- |
Conns Passive (CONNECTIONS_PASSIVE) | Number of times the TCP connection state transitioned directly from LISTEN to SYN-RCVD following the OS startup# | AVG | ulong | No | -- | -- |
Conns Reset (CONNECTIONS_RESET) | Number of times the TCP connection state transitioned directly from ESTABLISHED or CLOSE-WAIT to CLOSED following the OS startup# | AVG | ulong | No | -- | -- |
Interval (INTERVAL) | Collection interval time in which records were stored (in seconds). For a real-time report, the first value is 5. If records are summarized into a historical report, the total of the summarized records is displayed. | ADD | ulong | No | -- | RECORD_TIME (T1) - RECORD_TIME (T0) |
Record Time (RECORD_TIME) | Time at which the record was created | COPY | time_t | No | -- | -- |
Record Type (INPUT_RECORD_TYPE) | Record name. Always TCP6. | COPY | char (8) | No | -- | -- |
Segments Rcvd/sec (SEGMENTS_RECEIVED_PER_SEC) | Rate at which segments were received (segments/second). Includes those received in error and those that are on the established connection | AVG | float | No | -- | -- |
Segments Retransmitted/sec (SEGMENTS_RETRANSMITTED_PER_SEC) | Rate at which segments containing 1-byte or larger data that was transferred before were re-transferred (segments/second) | AVG | float | No | -- | -- |
Segments Sent/sec (SEGMENTS_SENT_PER_SEC) | Rate at which segments were sent (segments/second). Includes connected segments but does not include segments containing resent bytes. | AVG | float | No | -- | -- |
Segments/sec (SEGMENTS_PER_SEC) | Rate at which TCP segments were sent/received using the TCP protocol (segments/second) | AVG | float | No | -- | -- |
