The gurus have asked me to include the following scripting in our branch
office Nagios server configuration in order to monitor a remote co-location
site DNS server . I understand how/where to include the
host/service/contact/command definitions scripting, but where (what
file(s)) do I include the company_check_dns scripting command set procedure
listed near the bottom? I am running v3.0.2 on Fedora with the quick
installation setup.
*******************************************
We need to monitor DNS server at ip x.x.x.x both for ICMP and DNS.
Here are definitions for nagios that used to use, they will have to be
modified by you to work with the DNS server.
