Throttling alerts

PrivateZone throttles DNS queries from VPC endpoints (ECS instances and containers) based on the following QPS thresholds:

When an endpoint exceeds these thresholds, PrivateZone triggers throttling. You can receive alerts in two ways:

• Method 1: Enable DNS traffic analysis for PrivateZone to view throttling alert history in the global traffic analysis report.

• Method 2: Subscribe to events. PrivateZone sends alert notifications to specified contacts when throttling occurs. Configure this subscription as follows.

Procedure

1. Log on to the Cloud Monitor console.

2. In the left-side navigation pane, choose Event Center > Event Subscription.

3. On the Subscription Policy tab, click Create Subscription Policy.

4. On the Create Subscription Policy page, set Subscription Type to system event. Under Subscription Scope, set Product to PrivateZone, Event Type to Status Notification, Event Name to The DNS request QPS of the current account exceeds the limit, and Event Level to Warning. Keep Application Group as All Application Groups. Under Alert Suppression, select Trigger Immediately Without Suppression. Under Notification, select an existing notification configuration. Click Submit.

   Important

   To customize alert contacts, click Create Notification Configuration in the notification configuration section. Cloud Monitor automatically populates the Contact Group with your alert contacts. Manage notification configurations.

FAQ

Frequently receiving notifications for DNS operations not initiated by me

• Problem

  I receive frequent operation notifications from Alibaba Cloud DNS even though I have not modified any DNS records. These notifications are usually sent at a fixed interval.

• Cause

  This issue usually occurs because you have shared your AccessKey with a third-party service, such as a Dynamic Domain Name System (DDNS) or intranet penetration product. These services periodically call the Alibaba Cloud DNS API to modify DNS records and keep the IP address in sync, which triggers the operation change notifications.

• Troubleshooting

  1. Log on to the ActionTrail console and search for recent event logs where your AccessKey called Alibaba Cloud DNS APIs.

  2. Compare the API call times with the notification times to confirm if a third-party product triggered the notification.

• Solutions

  Solution 1: If you no longer use the third-party product or suspect that your AccessKey is compromised, disable or delete the AccessKey:

  Click your profile picture in the upper-right corner of the console and then click AccessKey. Find the AccessKey used by the third-party product and click Disable in the Actions column.

  Solution 2: If you want to continue using the third-party service but do not want to receive SMS notifications, disable the SMS channel for this notification.

  Go to the Common Settings page. Click the Product Message tab, find Alibaba Cloud DNS Operation Notifications, and clear the checkbox for the Text Messages channel.
