An alert is triggered
in the following way:
-
SAS BI Dashboard checks for a change in the indicator
data, updates to the indicator alert definition, or both. By default,
this check happens every 3 minutes. A SAS BI Dashboard administrator
can change this setting.
-
If the percentage of data points in the interval has
changed, the alert criteria are evaluated.
-
If the criteria are met, an alert is triggered and
a notification is sent to the subscriber.
Note: If the alert criteria
are met at the time that you create the alert, the alert is triggered
immediately. Afterwards, the alert is triggered only when the data
changes and the alert criteria are met.
When alert criteria are
evaluated, it is evaluated by subscriber. If a subscriber has multiple
alerts, each alert is evaluated for that subscriber before proceeding
to the next subscriber. Therefore, if there are a number of subscribers
for the same alert, it is possible for one subscriber to receive the
alert notification later than another subscriber. The lapse in time
might even cause the alert to be evaluated differently. However, a
group with multiple members is treated as one subscriber. Therefore,
it is more efficient to setup an alert for a group subscriber, than
to add multiple subscribers individually to an alert.
