Issue: An expected alert notification has not been received.
Resolution:
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.
