in 2.2.0RC1, they added multiple events in "event_queue". see doc/README.event_queue.
You can tune how many alerts will fire on a particular event. If you're in an
environment where you're alerting on more generic misbehavior and have some
back-end processor that can handle multiple alerts, it's pretty cool stuff.
Otherwise, it can be a little noisier than usual.
