Once you've provisioned Edge DNS, you can create alerts to monitor significant changes to your DNS traffic. Alerts provide automatic, real-time notifications for changes in your service use patterns.

Create a new alert

To create a new alert using the Alerts application on ​Control Center​, use the next instructions.

1. Log in to ​Control Center​ and go to ☰ > COMMON SERVICES > Alerts. The Alerts page opens.

2. Click Create New Alert. The Create New Alert wizard opens.

3. From the View alert types for menu, select Edge DNS.

4. Select the desired alert type from the options by clicking the radio button adjacent to it. Alternatively, you can enter an alert type in the Filter alert types text box. A brief description of the alert type opens, which includes the products the alert type can be applied to. The following alerts can be applied to Edge DNS:

   • Certificate's domain is blocked. Notifies you when a certificate cannot be issued because the domain is blocked by the certificate authority Let's Encrypt.

   • ​Control Center​ Event. Notifies you when configuration or provisioning changes have been made in ​Control Center​, such as a change to your valid domains, the uploading or activation of a configuration file, or a change to a user's permissions. The notifications are sent with a six-hour delay.

   • DNS does not contain an authoritative certificate authority. Notifies you when a certificate cannot be issued because Let's Encrypt is not an authorized certificate authority in your DNS.

   • Domain validation failed. Notifies you when a certificate cannot be issued because DNS validation failed.

   • Expired default certificate. Notifies you that a default certificate is expired.

   • Expired default certificate removal. Notifies you that an expired default certificate will be removed from the network.

   • Failed Zone transfer (Critical). Notifies you when no Zone Transfer Agents (ZTAs) are able to do zone transfers, indicating that the system is potentially serving stale DNS information.

   📘

   This alert indicates a very serious condition.

   • High number of NXDOMAIN responses. Notifies you when the volume of NXDOMAIN responses for a particular zone goes above a certain threshold.

   📘

   This alert provides valuable performance-monitoring information.

   • High origin hits. Notifies you when the number of hits for the specified CP codes exceeds a specified threshold.

   • High Traffic - DNS. Notifies you when the volume of DNS traffic for a particular zone goes above a certain threshold.

   📘

   This alert provides valuable performance-monitoring information.

   • SLA Availability. Notifies you when the SLA availability falls below a configured percent.

   • Zone Approaching Resource Record Limit. Notifies you when an Edge DNS zone has grown in resource records up to nearly the limit allowed for the zone.

   • Zone SOA Ahead. Notifies you if a Zone Transfer Agent (ZTA) detects that the master name servers advertise an SOA serial number that is less than what the ZTA already has (received by a previous zone transfer). This alert can indicate that the master name servers were improperly updated; as a safety mechanism, the ZTAs refuse to perform a zone transfer of a presumed stale zone.

5. Click Next to configure the selected alert.

6. Complete the Create New Alert wizard pages using the onscreen help for guidance.

7. Click Submit.

Alerts API

To create your own automated mechanism to manage your alerts outside of ​Akamai Control Center​, the Alerts API is available. This API provides a programmatic interface to the same functionality available in ​Control Center​.
