if your hosts.cfg file looks like this:
0.0.0.0 foo # dns 10.1.1.2 bar # testip ntp
and the DNS lookup for foo is 10.1.1.1, what xymon command would I issue in a script to get a list of the IP addresses Xymon has associated with each host?
so, for the above example, the result would be:
10.1.1.1 foo # tests 10.1.1.2 bar # tests
I'm looking for a way to get the IP addresses Xymon is using for each host.
It depends a little on what you want. In a real sense, xymon doesn't systematically maintain a list of addresses used for the host. The only component that looks them up (xymonnet) does a fresh DNS lookup for each one with "0.0.0.0" that it finds. It's using the c-ares library for that, but it basically follows the same rules as the normal system resolver. It shouldn't be any different than scripting a 'host $SERVERNAME' call against hosts with no IP configured and parsing the result. Since xymonnet is executed, and then exits and is restarted at the next poll cycle, there's nothing that can really get cached either.
If you want to see what IP actually *happened*, you could try something like this to get at the results of the 'conn' tests if you're using 4.3.18 or higher.
xymon localhost "xymondboard test=conn fields=hostname,msg" | perl -pe 's/^([\w.-]+)\W.*&\w+\s([\d.]+).*/\1 \2/'
All of the other ways of pulling data from xymond (like below) will just return the configured IP itself... the 0.0.0.0.
xymon localhost "hostinfo fields=XMH_HOSTNAME,XMH_IP"
