alarm event types (Event Chinese Name) | Event Name | Event Description | Handling Method and Suggestion |
DDoS attack | DDoSAttack | EdgeOne detected that the IP address serving you is under DDoS attack. | Please pay attention to your business availability, and you can view the L3/4 DDoS attack protection bandwidth metrics card on the EdgeOne console - metrics analysis page. Click the top number of DDoS attack events tab to view the corresponding attack event details. |
DDoS attack causes blocking | DDoSAttackBan | Due to being subjected to a DDoS attack, the IP address serving you has been blocked by the operator. | |
HTTP request surge | HTTPRequestBurst | EdgeOne detected a surge in HTTP requests for the domain, which is suspected to be under HTTP DDoS attack. | 1. Please pay attention to your business availability. You can view the details of recent traffic and request counts on the EdgeOne console - metrics analysis page to determine whether the traffic surge belongs to normal business. 2. If you determine that the traffic surge does not belong to normal business, and the current security policy does not cover the characteristics carried by this attack, it is recommended to modify and tighten the Web protection policy. 3. If you determine that the traffic surge belongs to normal business, you can ignore this alarm. It is recommended to relax the Web Protection - Adaptive Rate Limiting Level or switch to observation mode. |
Web Security Monitoring | WebSecurityMonitoringEvent | EdgeOne detected requests that hit the Web Security Monitoring Rules, which may constitute malicious Web attacks affecting website security. | 1. View attack details via Web Security Analysis. 2. Analyze the trigger reason based on the Web protection rule ID. If you need to adjust the alarm rules, refer to the Web Security Monitoring Rules. |
Suspected fraudulent traffic (Based on intelligence database detection) | BandwidthAbuseBasedOnClientReputation | EdgeOne detected abnormal access traffic matching blacklisted IPs in the feature database, suspected of fraudulent consumption of bandwidth resources. Detection timeliness: T+1 day. | 1. Check the traffic status of the corresponding domain to confirm whether there is an unexpected traffic surge. 2. If fraudulent activity is confirmed, block the suspected client IPs initiating the traffic abuse via the Rule Engine - HTTP Response or Web Protection - Basic Access Control feature. 3. Enable the Web Protection - Traffic Anti-Scrubbing feature to automatically protect against fraudulent traffic. 4. Adjust the rule level of the Web Protection - Adaptive Rate Control feature to "Adaptive - Moderate" or "Adaptive - Urgent". 5. For large file resources, limit the access frequency via the Web Protection - Precise Rate Limiting feature. 6. Configure the Usage Capping Policy based on your business needs to automatically suspend domain services before high bills are incurred. 7. For other measures (such as Token authentication, UA allowlist and denylist, and rate limiting for suspicious UAs), see the EdgeOne Anti-Scrubbing Practice Tutorial. |
Managed Ruleset Update | WebSecurityManagedRulesNewVersion | The Web Protection Managed Ruleset has been released in a new version, which may cover new vulnerability protections or rule optimizations. | 1. It is recommended to log in to the EdgeOne console and review the new version rule descriptions in the Managed Rules of the specific Web Protection policy. 2. If Automatic Updates are not currently enabled, please evaluate whether to upgrade the current ruleset to enhance security protection. |
Origin IP address Change | IPAclCIDRsUpdate | EdgeOne detected a change in the Back-to-Origin IP address, which may affect the stability of origin server connections. | 1. Verify whether the updated Back-to-Origin IP address is authorized by your origin server. 2. Please refer to Updating Back-to-Origin IP Ranges to promptly update your origin server firewall settings, preventing service disruption caused by back-to-origin failures. |
NS Servers Take Effect | NSModificationTakenEffect | The site NS servers you added in the EdgeOne console have taken effect. | This is a system notification indicating that the DNS server has been updated. You can continue to complete operations such as adding DNS records, accelerating domains, and configuring HTTPS certificates: 1. Configure DNS records. For details, see Configuring Domain DNS Resolution Records. 2. Onboard your domain to EdgeOne for acceleration. For details, see Adding an Accelerated Domain. 3. Configure HTTPS certificates. For details, see Quickly Enabling HTTPS Access with Free Certificates. |
Domain Name Filing Expiration and Deactivation Warning | DomainOfflineHeadsUpDue2IcpFilingExpiration | Detected that your domain name's ICP filing information is about to expire, which may cause service interruption. | 1. Please handle the domain name ICP filing issue. Refer to the Filing Guide to complete the filing process. 2. After domain name ICP filing is restored, resume domain services via the EdgeOne console. |
Domain Name Filing Expiration and Deactivation | DomainOfflineDue2IcpFilingExpiration | Domain name ICP filing has expired or become invalid, and related services have been suspended. | 1. Please handle the domain name ICP filing issue. Refer to the Filing Guide to complete the filing process. 2. After domain name ICP filing is restored, resume domain services via the EdgeOne console. |
Site acceleration region switch caused by ICP filing invalidation | SiteAccelerationRegionSwitchDue2IcpFilingExpiration | Domain name ICP filing is abnormal. Site acceleration service has been automatically switched to restricted regions (such as outside Mainland China). | 1. Please first resolve the ICP filing issue. Refer to the Filing Guide to complete the filing process. 2. After the ICP filing is restored, manually switch the acceleration region back to the original region (such as Mainland China) via the EdgeOne console. |
Site violation blocking | SiteViolationBan | Your site has been blocked by the system due to violation of service terms or laws and regulations. | If you have any objections to this, please submit a ticket to contact customer service for feedback and processing. |
Account violation blocking | AccountViolationBan | Your Tencent Cloud account has been blocked due to serious violations. All EdgeOne site acceleration services under the account have been terminated, and you cannot add new sites. | If you have any objections to this, please submit a ticket to contact customer service for feedback and processing. |
Usage threshold alarm | UsageThresholdAlarm | The current service usage has exceeded your configured warning threshold. If it subsequently reaches the upper threshold you configured, the domain service will be suspended and return a 403 status code. | 1. Please note the impact of usage capping on your current services. 2. To adjust the usage capping threshold, see Usage Capping Policy. |
Usage triggered capping | UsageQuotaLimitReached | The current service usage has reached your configured upper limit. The service has been suspended, and domain requests will return a 403 status code. | 1. If you need to restore, please navigate to EdgeOne console > Domain Management to manually enable domain acceleration. 2. To adjust the usage capping threshold, see Usage Capping Policy. |
Add-on pack exhausted | AdditionalPackageExhausted | ||
Add-on pack expired | AdditionalPackageExpired | ||
Add-on pack auto-renewal | AdditionalPackageAutoRenew | 1. (Successfully renewed) Log in to EdgeOne console > add-on pack management to view the validity period update status of the add-on pack and confirm the deduction records. 2. (Renewal failed) If the renewal fails due to insufficient account balance, recharge promptly and check the auto-renewal settings to prevent service disruption. 3. You can manage the auto-renewal switch for add-on packs in EdgeOne console > add-on pack management. | |
Plan not used | UnusedPlanReminder | The plan you purchased has not been enabled or is about to expire and has not been fully utilized. | 1. Log in to EdgeOne console > plan management to check the plan status and usage. 2. If you plan to use it, please configure the relevant services as soon as possible. |
Plan not renewed automatic downgrade | AutoDowngrade2FreePlanDue2NonRenewal | Your paid plan has been automatically downgraded to the free tier due to untimely renewal. | 1. The free tier has limited features. We recommend that you log in to EdgeOne console > plan management to upgrade your plan as soon as possible and restore the benefits of your original paid plan. 2. If you do not require paid services, you can continue using the free tier, but please note the feature and quota limitations. |
