Throttling alerts

PrivateZone sets thresholds for the number of DNS queries that can be initiated by endpoints such as ECS instances and containers in a VPC:

If the number of DNS queries from an endpoint in a VPC exceeds the specified threshold, throttling is triggered. You can receive throttling alerts using one of the following two methods.

• Method 1: Enable network traffic analysis for your private zone. You can then view the alert history in the global network traffic analysis report.

• Method 2: Subscribe to events. When DNS query throttling is triggered for a private zone, an alert notification is sent to the specified contacts. The following procedure describes how to configure this method.

Procedure

1. Log on to the Cloud Monitor console.

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

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