Re: Is there a way to filter out all alarms who has been unblocked a certain date?

By 'blocked' do you actually mean 'disabled'?

Like the alarms had been disabled indefinitely previously, and this person just re-enabled them all?

 

I think there is possibly an Event Journal entry added at the time that the user would have enabled the alarm.  You could check one such known point to see about the Event Journal entry description at the time.

If you then searched for the entire Event Journal for this event message (over the time you think the user would have done the action, and perhaps like 10 minutes after, to allow for any propagation times).

 

As a general situation however, it's not advisable to have alarms disabled for a prolonged period of time.

Often in systems we impose a set limit on the alarm disable duration (to like 4 weeks), since alarms should only be disabled whilst the cause of the invalid alarm is addressed (i.e. sensor is fixed or similar).

If there is an alarm that you don't ever want, then it simply shouldn't be an alarm.  You should turn off the alarm configuration for it.
