What is your opinion?
That you've been staring at the problem from waaay too close :^)
Seriously, all you need to do is to define (in Nagios, not
necessarily in the DNS, although that probably wouldn't hurt)
separate hosts for the different interfaces, a la
define host{
use corp-host
host_name mink-ge0
alias mink
address 10.10.10.10
}
define host{
use corp-host
host_name mink-ge1
alias mink
address 10.10.10.10
}
Once you have that, you just define the services for each "host" as
appropriate.

[Nagios-users] Service on an IP address different from the host
Hi,
some systems I am responsible for have multiple IP addresses, with
services that are not running on all IP addresses. I thus need service
definitions that don't check the service on the host address, but on a
dedicated "service address" while still being associated to the host
which has a different address.
I have come up with various ways to do this, each of them ugly, but
differently so.
(1)
Duplicate each command definition for a service check like
define command{
command_namecheck_http
command_line$USER1$/check_http -H $HOSTADDRESS$
}
define command{
command_namecheck_http_addr
command_line$USER1$/check_http -H $ARG1$
}
(2)
One other idea I have come up with would be having a thing like an "optional
argument", which could be configured like
define command{
command_namecheck_http
command_line$USER1$/check_http -H $IFDEF $ARG1$$ $ARG1$ $ELSE$
$HOSTADDRESS$ $ENDIF$
}
(3)
A different approach (which is what I did back in netsaint days) was a
metaplugin, which allows command configuration like
define command {
command_namecheck_http
command_line$USER2$/modify_address $HOSTADDRESS$-$ARG1$
$USER1$/check_dns_random modify_address
}
which allows service definitions like
define service {
...
check_command check_http
}
which checks the service on $HOSTADDRESS$ and
define service {
...
check_command check_http!192.168.130.5
}
which checks the service on 192.168.130.5.
In the example, the metaplugin replaces the occurence of the string
modify_address with $HOSTADDRESS$ if $ARG1$ is empty, and $ARG1$
otherwise. This has the advantage of having a very straightforward
service configuration, at the price of having a confusing and complex
command definition which does not use nagios standard mechanisms.
(4)
The last approach would be to have host definitions for both IP
addresses, but that would probably be confusing for notification
recipients who are not so intimately familiar with system
architecture.
Which approach would, in your opinion, be appropriate for a new
installation? I am currently inclined towards (4).
What is your opinion?
Greetings
Marc
