I would suggest you use custom object variables
(http://nagios.sourceforge.net/docs/3_0/customobjectvars.html). This is
a nagios 3 feature, so if you're on 2.0 you'll need to upgrade.
Basically, you can define custom variables into
hosts/services/whatever. So you'd have a custom object var in the host
define host {
name UPS-thing
_OIDS <List of OIDs Here> <-- This being the custom variable that
you define.
}
and in your service you'll have
define service {
name snmp-check
check_command check_snmp!$_HOSTOIDS$ <-- Use it like so
}
