Description
Pending billing
The elastic bandwidth usage has been recorded, but the bill has not been formally generated. You can click Details in the View column to query the actual service traffic details in the Details dialog box.
NoteIf you have any questions about the actual bandwidth usage, provide feedback promptly. If the bill usage is confirmed to differ from the actual bandwidth usage, Anti-DDoS Proxy sets the status to Billing Terminated (the bill is closed without incurring actual charges).

Procedure
Log on to the Anti-DDoS Proxy console.
In the top navigation bar, select the region of your instance.
Anti-DDoS Proxy (Chinese Mainland): Choose the Chinese Mainland region.
Anti-DDoS Proxy (Outside Chinese Mainland): Choose the Outside Chinese Mainland region.

On the System Logs page, select Alerts on Exceeded Upper Limits. Specify the IP address to query and the time range to view the alerts on exceeded instance specifications. The following table describes the values in the Description column and Details column:
Description
The Anti-DDoS IP address and event type that triggered the alert. Event types include service bandwidth, new connections, and concurrent connections. An alert is generated when the specification for an event type exceeds the purchased specification.
Details
Click View in the Details column of an alert to view the full alert details.
For example, if concurrent connections exceed the specification, you can see from the alert details that the number of active connections has exceeded the concurrent connection limit, triggering the alert.
Query destination rate-limiting events
When metrics such as new connections, concurrent connections, or service bandwidth significantly exceed the instance specifications, a rate-limiting policy is triggered. This affects your services and generates a destination rate limit event.
If rate limiting is triggered by normal service traffic, upgrade your instance as soon as possible. For more information, see Upgrade an instance.
If rate limiting is triggered by a DDoS attack, adjust your protection settings promptly. For more information, see Protection settings.
Applicable scope
An Anti-DDoS Proxy (Chinese Mainland) or Anti-DDoS Proxy (Outside Chinese Mainland) instance is purchased. For more information, see Purchase an Anti-DDoS Proxy instance.
