There are two scenarios, and the solution depends upon what you want to do.
The first is where Omnibus is the repository, and you want Snort to only
detect certain events (ie. the .ida attempts). To do this, create a
local.rule file that contains only the rules you're interested in, and
comment out all the other include statements in snort.conf. Snort will then
only detect the signatures in local.rules, and send them all to Omnibus via
SNMP traps.

The second scenario is to have Snort keep all events locally, and send
certain ones to Omnibus. In snort.conf, create a ruletype that sends events
to events to Omnibus as well as whatever you're doing to store events
locally (there are examples in the file for doing this), and change the
".ida" rules in the .rules files to use this logging ruletype instead of
