The total number of segments sent, including those on currently established connections but excluding
those containing only retransmitted bytes. Segment is the official TCP name for what is casually called
a data packet.

one or more previously transmitted bytes. Segment is the official TCP name for what is casually called
a data packet.
TCP Timeout Min
The minimum value permitted for TCP retransmission timeout, measured in milliseconds.
TCP Timeout Max
The maximum value permitted for TCP retransmission timeout, measured in milliseconds.
TCP Connection Limit
The limit on the total number of TCP connections that the system can support. A value of
-1
means there
is no limit.
TCP Active Opens
The number of TCP connections that went directly from an unconnected state to a
connection-synchronizing state, bypassing the listening state. These connections are allowed, but they
are usually in the minority.
TCP Passive Opens
The number of TCP connections that went from a listening state to a connection-synchronizing state.
These connections are usually in the majority.
TCP Attempt Failures
The number of TCP connection attempts that failed. Technically this is the number of TCP connections
that went to an unconnected state, plus the number that went to a listening state, from a
connection-synchronizing state.
