multiple IPs for a host?

[Eric Loyd]

If your machines are consistently named BOX and BOX-MGT (or something 
like that) you can teach your ping script to ping $HOSTADDRESS$-MGT, 
which means you don't have to do anything other than add services to 
BOX.  Or vice-versa.  Whatever is appropriate.

If your machines are not consistently named, you could make your 
check-host-alive be a script which does a table lookup of some sort to 
get the appropriate name to ping and continue on that way.

Nagios need never know there are two interfaces unless you want it to know
.
