"trace" in hosts.cfg and a suitable entry in xymonserver.cfg should be all
you need. (You can also just add --trace to the xymonnet options in
tasks.cfg.) Since you're running as the 'xymon' user (presumably), don't
forget privilege escalation for traceroute in TCP mode.


tasks.cfg:      CMD xymonnet --report --ping --trace --checkresponse
xymonserver.cfg:TRACEROUTE="sudo /bin/traceroute -I"
