Hi,
       We are monitoring a particular port that we are having issues
with. 8022, it's a proxy port for HP NA.

       Anyway, I have an expect script that goes in and tests the
functionality of the port. But when it starts to go bad, this script get
stuck in TIME_WAIT, along with the users connecting to the port.

why not use ssh:8022:s in hosts.cfg ?

       So, can I look at the port data before I try connecting, and if
there are a bunch of TIME_WAIT connections, just skip the test entirely?

       I'm running the test from the xymon server, so I was thinking of
pulling the data out of xymon directly. Would that by xymoncmd?

if you like to pursue your method and just want to count the number of
TIME_WAIT for port 8022, you can run something like this from xymon
server

xymon localhost  "clientlog host.example.net section=ports" | grep
8022 | grep TIME_WAIT

This works too:

     /home/xymon/server/bin/xymon localhost "xymondlog
server.domain.com.ports"
