There are many factors that can affect
alert notifications. For example, system administrators for SAS Visual Analytics can set a property for
how frequently the system checks to see whether the alert condition has been met.
And, alert notifications are not sent if a server is down.
The timing of when alert notifications are sent can vary depending on when the alert
condition is met. For example, suppose
that you specify that alert notifications are sent every five days. The alert condition
is met for the first time at 10:00am on September 2. After that, the system continues
to check for the alert condition based on the hour or minute value that you specified
for the
Query the system every field. Because the frequency is set to five days, no alert notifications will be
sent between 10:01am on September 2 and 9:59am on September 7. This is the case, no
matter how many times the alert condition is met during that timeframe. At 10:00am
on September 7, if the alert condition is met, then another
alert notification is sent, and the five-day countdown starts again. On the other hand, if the alert
condition has not been met at 10:00am on September 7, then no alert notification is
sent. However, now that five days have passed, an alert notification is sent as soon
as the alert condition is met again. Suppose that an alert notification is sent at
2:00pm on September 10. After the alert notification is sent, the five-day countdown
starts again, and the earliest the next alert notification can be sent is 2:00pm on
September 15. If you modify the notification frequency, then the notification history
is reset.
You might not receive an alert notification as soon as the alert condition is met
because of the hour or minute value that is
set in the Query the
system every field in the designer. For example, suppose
that you set the value in the Query the system every field
to 1 day. If the alert
condition is met one hour after the system check is done, then it
will be another 23 hours before the system checks for the alert condition
again and sends an alert notification.
