Measurement descriptions:
TCP 1: The total number of segments sent, including those on current connections but excluding
those containing only retransmitted octets.
TCP 2: The total number of segments retransmitted – that is, the number of TCP segments
transmitted containing one or more previously transmitted octets.
TCP 3: The total number of segments received, including those received in error. This count
includes segments received on currently established connections.
TCP 4: The number of times TCP connections have made a direct transition to the SYN-SENT
state from the CLOSED state.
TCP 5: The number of times TCP connections have made a direct transition to the SYN-RCVD
state from the LISTEN state.
TCP 6: 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.
TCP 7: The number of TCP connections reaching the ESTABLISHED state.
TCP 8: The number of TCP connections or connection attempts that have been closed. Drops are
closes initiated at the local end of the connection.
TCP 9: The number of connections closed that never reached ESTABLISHED state.
TCP 10: The count of window size updates based on round trip estimate.
TCP 11: The number of time expirations while awaiting an expected ACK.
TCP 12: The number of connections dropped because of the above timeout
TCP 13: The number of time expirations while waiting for window to open
TCP 14: The number of connections dropped because of the above timeout
TCP 15: The number of keep-alive timer expirations on idle connections
TCP 16: The number of connections dropped because of the above timeout
