I use the check_ping plugin from the 1.4.0 beta that support a 
comma-separated interface list. This allows me to define a host as 
comprised of the 3 interfaces. I then make the individual interfaces 
into hosts that are dependent on those primary hosts. I do not check 
multiple interfaces for anything other than ping.

There was a discussion in this topic some time ago, and there was a 
general realization that check_ping is the only plugin that urgently 
needs to support multiple interfaces. I think this thread brought up the 
idea of a general wrapper that could make any plugin act as it it 
supported multiple interfaces -- I think that is an excellent approach. 
 From there, we could move on to adding the capability to check_tcp and 
check_http. But the complexity of handling it on a case-by-case basis 
may not be worthwhile for all the plugins. So at some point, we may need 
to extend netutils.c to make general way of handling multiple interfaces 
-- but I have not thought at all about what such changes might look like.

Hopefully that helps a little, and thanks for sustaining this thread 
which has brought some light onto the topic, for me at least.
