No, all of the metric conditions should use dampening just fine.
Availability is a bit different because of the way we only signal
changes in availability and don't supply a constant stream of
availability (this is for efficiency). But metrics are reported as
scheduled, whether the value changes or not.
Does this happen only when the alert definition is derived from a
template? If you define the exact same alert def at the resource level
does the dampening work? That would be very strange but I'm just checking.
Can you post the exact alert def conditions and the dampening rule you
have in effect.

Hi!
Thanks a lot, it does help me to understand things! My problem may be
rooted in the concept of "discrete events"!
anyway... is it possible, that the alert "process CPU consumption
(percent) is higher than a given value" is affected by "being a
discrete event"? I receive all alerts in every 20 minutes (or whatever
the measurement interval is).
The templates are itemized correctly!

Hi Attila, two things. First, what type of alert conditions are
you using? Certain conditions, most notably Availability
conditions like GOES DOWN, ignore dampening because they are
discrete events. Second, there was a recent bug fix in the area
of dampening. The hourly data purge was negating some of the
dampening state, so dampening that crossed the top of the hour may
have been affected. This fix will be in 4.10.
Do either of these things, maybe explain what you are seeing?
Also, you are saying that this is dampening at the alert template
level? Check to ensure the dampening is also reflected at the
resource level by looking at the alert definition that was
propagated down from the template to one of the resources of the
relevant type.
