I was just trying to explain how the deduplication mechanism works so  
that you can make it work the way you want it to. The most important  
thing to understand is that if the following fields match between two  
events, the existing event's count will just be increased instead of  
creating a new event.

device
component (can be blank)
eventClass
severity
eventKey (summary is used if eventKey is blank)

So in the case of the SNMP traps that your script is sending, all of  
these fields are matching. This leads to the deduplication you're  
experiencing. The high-level answer to any question like this is that  
you need to make sure that at least one of these fields is different  
between your events if you want them to remain distinct events. The  
most common ones to alter are the eventKey or summary. My previous  
example suggested altering the summary because I was assuming that  
your events have a blank eventKey.
