Either fix the DNS issue, or specify the IP-address to use for the http test with the http://abixymon.mtncameroon.net=10.0.0.1/ syntax to override the DNS lookup.
Eureka! Didn't know about the "=ip" syntax, so this post sent me to the manpage. This is perfect for our situation of Internet-facing virtual hosts with private addresses in the internal split DNS. Up to now, if a NAT failure occurred for one of these, we didn't necessarily know, because we were testing via the RFC1918 address. Couldn't use straight-IP URLs because of virtual host settings and rewrite rules.
