You can't do it on the Xymon server, because the data is truncated 
before reaching the Xymon server.

But you can edit the xymonclient-<OSNAME>.sh script running on the 
haproxy-server. Just change the "netstat" command and add a "| grep -v 
TIME_WAIT" to filter out the time-wait entries in the netstat output.
