tcp traceroute

In the same way that the conn test can be asked to "trace" by performing

traceroute upon failure, I would like to perform a TCP traceroute when a
TCP test fails with "no route to host". I expect this isn't built right
into Xymon now but has anybody got any pointers on what to hack to
implement this myself?

Magic built in not tacked on later!!

From the hosts.cfg man page:

trace
     If the connectivity test fails, run a "traceroute" and include the
output
     from this in the status message from the failed connectivity test.
Note:
     For this to work, you may have to define the TRACEROUTE environment
     variable, see xymonserver.cfg(5)

Is that what you are looking for?

"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"
