Question:  

How long does nas's storm protection stay active?
 
 

Answer:

When 3000 messages have accumulated in less than (or equal to) 5 minutes, a storm has begun.
Prior to that point all alarms are published with the ‘alarm2’ subject for Nas to pickup.
After that point (and till the storm has died out) the messages are published with a ‘NAS_QUARANTINE” subject.    
Keep in mind these times are asymmetric.
If you had a storm of 2990 alarms in the first 10 seconds, then 10 more alarms occur at 4 minutes and 50 seconds,
the storm will be over 10 seconds after it started.
