Chapter 13 Monitoring

Monitoring Statistics MIB-II TCP/UDP

TCP Segments Transmitted

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.

TCP Segments Retransmitted

The total number of segments retransmitted; that is, the number of TCP segments transmitted containing 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 -1means 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.
