I'm developing a Big Brother monitoring script that will collect and display
the output from the 'ipfstat -s' command, and I'd like to include descriptive
text for each of the statistics. Can anyone provide me with brief descriptions
of the following statistics?
IP state statistics:
TCP
Running total number of TCP states added
UDP
Running total number of UDP states added
ICMP
Running total number of ICMP states added
hits
Running total of the number of times a packet matched state in the table
misses
Running total of the number of times a packet did not match state in the
table
maximum
Running total of the number of times adding packet state has failed
because the state table is too full
no memory
Running total of the number of times adding packet state has failed
because no memory has been available to put new state information in
max bucket
Running total of the number of times adding packet state has failed
because the has chain is at its maximum size
active
Current number of live state sessions
expired
Running total of state sessions removed from the active table because
they "timed out" from their current state (all non-TCP plus TCP that
doesn't "close")
closed
Running total of TCP state sessions that close gracefully, as per the RFC.
State table bucket statistics:
in use
Number of top level buckets in the hash table being used
bucket usage
The above number as a percentage of the available slots
minimal length
Shortest hash bucket chain
maximal length
Longest hash bucket chain
average length
Average length of the chains in the hash table
