An entry in the bb-host file like:
192.168.10.10 bambam # dns=fred
will perform a DNS query against the server bambam for the hostname: fred. The way I understand it is if a response is received, the DNS is considered good.
I would like to know if here are any options to verify the result. In my particular case, we want to query against a "Split DNS" server and confirm the correct IP is being returned in the A record. So,
192.168.10.10 bambam.dom.com # dns=fred.dom.com
71.137.200.10 bambam.dom.com # dns=fred.dom.com
The first entry should return: 192.168.10.15
The second entry should return: 71.137.200.15
If DNS views are broken, the 2nd entry may return: 192.168.10.15 If so, I want to get a page so DNS can be fixed.
Don't know how to do what you want the way you want, but you'll need "testip" on those bb-hosts entries or they're both going to test whatever the Xymon server returns for bambam.dom.com.
A possible workaround for what you want: is it possible to insert an A record into the external zone for a host name that doesn't exist in the internal zone? If a test on that failed, you'd know that either the external DNS server was down or that the internal DNS zone was incorrectly being used. You'd probably want a page either way.
