Configuration Item | Description |
Scope of Effectiveness | Choose the scope of effectiveness for the cap policy: Site: All subdomains under the site share a single cap policy. Subdomain: All selected subdomains share a single cap policy. |
Statistics Period | Choose the data statistics period for the cap policy, and periodically compare the statistical data with the capping threshold: 5 minutes: Statistics for usage generated within 5 minutes. Hour: Statistics for usage generated within 1 hour. Day: Statistics for usage generated within 24 hours. Note: When the statistics period is set to "5 minutes," it will calculate usage for each complete 5-minute interval. For example, if you configure and save a L7 traffic capping policy at 15:26:00 on October 25, 2023, the first 5-minute interval will calculate L7 traffic from 15:25:00 to 15:29:59, and the second 5-minute interval will calculate L7 traffic from 15:30:00 to 15:34:59, and so on. When the statistics period is set to "1 hour," it will calculate usage for each complete 1-hour interval. For example, if you configure and save a L7 traffic capping policy at 15:26:00 on October 25, 2023, the first 1-hour interval will calculate L7 traffic from 15:00:00 to 15:59:59, and the second 1-hour interval will calculate L7 traffic from 16:00:00 to 16:59:59, and so on. When the statistics period is set to "day," it will calculate usage for each complete 24-hour interval. For example, if you configure and save a L7 traffic capping policy at 15:26:00 on October 25, 2023, the first day interval will calculate L7 traffic from 00:00:00 to 23:59:59 on October 25. When usage exceeds the set threshold during the statistics period, the service will be disabled. It is recommended to adjust the cap threshold first, then go to the domain management page to re-enable the domain name. Otherwise, the next scan will disable the service again because the usage has exceeded the current cap threshold setting. |
Cap Configuration | Choose the policy type for cap configuration. When both the traffic,bandwidth and request policy for the same domain exist simultaneously, triggering the threshold for either will disable the domain service: L7 Traffic: represents setting the highest cap threshold for L7 traffic, with the option to choose units in MB, GB, TB. HTTP/HTTPS Request Number: represents setting the highest cap threshold for HTTP/HTTPS request numbers, with the option to choose units in ten thousand times, million times, and hundred million times. L7 Bandwidth: represents setting the highest cap threshold for L7 bandwidth, with the option to choose units in Mbps, Gbps, and Tbps. |
Exceeding Threshold | Service Deactivation: indicates that when the cap threshold is triggered, service will be deactivated for all subdomains within the effective scope. |
Alert Threshold | When the usage/usage threshold within the statistical period reaches the configured alert threshold (10% - 90%), an alert message will be issued. Note: If the alert threshold is already enabled: due to a scanning granularity of 5 minutes, if there is a significant increase in usage within a short period and the value is large, it is possible that the previous scan has not triggered the percentage alert threshold, and the next scan directly reaches the access threshold. In this scenario, both percentage and access threshold alert notification messages will be sent. |
