Single Host, Multiple IPs using IP Aliasing

Folks,

I'm having an interesting conundrum that I haven't seen any posts about. We have multiple machines configured such that they have multiple IPs aliased to the same ethernet interface e.g. bgeo, bge0:1, bge0:2 up to at least 41 on the one machine I'm looking at right now. These IPs are all in the same network but aren't contiguous or have any other pattern to them. Each IP is in DNS and has a different hostname associated with it. There is a web server listening on each IP. Here's what I'm trying to do:

1. Configure the host for monitoring using SNMP - works to get CPU, Disk and Memory just fine.

2. Configure Apache monitors to check status of the Apache server running on each IP on the same machine. Every time I attempt to create such an Apache monitor it doesn't put it within the machine's monitor. Instead it creates a new host monitor with the IP I specified and puts the Apache monitor inside that host. Not the behavior I want.

Any thoughts on how I can achieve what I want?

Thanks!
