You can use notification throttling to limit the number of alert email actions (notifications sent by email for a fired alert) that are issued in a 15 second interval.

When the threshold you specify is reached, vCenter Hypericstops sending email alert notifications and instead sends a summary of alert activity every ten minutes to the recipients you specify.

After starting to throttle, vCenter Hyperic re-evaluates notification volume for fired alerts every 10 minutes; when it determines that the per interval volume of individual notifications that fired alerts would generate is less than the configured threshold, vCenter Hyperic resumes sending individual notifications.

In the Notification Throttling Configuration Properties section of the Server Settings page:


Click the Notification Throttling ON control.


In the Threshold field, enter the maximum number of notifications you want sent in a 15 second interval.


Enter one or more email addresses in the Notification Email(s) field.
