Broker Queue Rule - Help

I want to accomplish the following:

If there are more than 75 documents queued in Broker client queues (Cummulative) for the past 30 minutes, send an alert. I created a rule as below but I am not sure if it is correct, as it doesn’t seem to be sending me any notifications.

Summary Rule
Sticky
Intervals Before True: 6
Simple Expression
Property
OMI
OMIBroker stats:numEventsQueued
reading.value
GREATER THAN OR EQUAL TO
Literal
75.0

The rule history shows data as below. I think it is showing how much was queued but doesn’t take into consideration what is already there in the queues. I have total around 12,000 documents on my dev broker which have not been retrieved.

Also, is there any way I can manipulate the alert method to instead of sending an email, I can write to a file or route to some other option to be used by a incident tracking application?
