This section allows you to configure the threshold for email alerts. This setting helps in avoiding spamming the user’s inbox with repeated alerts.
Count Threshold - Specify the minimum number of alerts (of the same type) to be received by the WCC before sending an email notification.
- Time Threshold (minutes) -Specify the time interval to wait before sending an email notification for the same alert type.
Example: Consider "Time Threshold" is set to 60 (minutes) and "Count Threshold" is set to 30. If the same alert is received more than 30 times within 60 minutes from the same WAF, an email notification will be sent by the WCC and a new 60 minutes window begins. At the end of 60 minutes, if the "Count Threshold" is not exceeded, the alert count is reset to zero (0).
