Simple Log Service:Usage notes

Last Updated:Aug 02, 2023

Simple Log Service and Anti-DDoS Pro of the former version jointly launch the log analysis feature that allows you to collect, query, analyze, transform, and consume website access logs and HTTP flood attack logs in real time. You can use the log analysis feature to troubleshoot website access issues, trace HTTP flood attackers, and analyze website operations. This topic describes the assets, billing, and limits of the log analysis feature.

Note

Anti-DDoS Pro of the former version has been upgraded to Anti-DDoS Pro of the new version. The console of Anti-DDoS Pro of the former version is available only if you purchased Anti-DDoS Pro instances. You can no longer purchase instances in the console of Anti-DDoS Pro of the former version.

Benefits

  • Ease of use: The feature allows you to collect logs for Anti-DDoS Pro of the former version in real time after simple configuration. Log collection is automatically enabled for websites after the websites are added.

  • Real-time analysis: The feature provides real-time log analysis and out-of-the-box dashboards. You can obtain information about the HTTP flood attacks on your website and access to your website.

  • Real-time alerting: The feature supports custom quasi-real-time monitoring and alerting for specific metrics. You can respond to exceptions in critical workloads at the earliest opportunity.

  • High compatibility: The feature is compatible with solutions such as stream computing, cloud storage, and visualization. This allows you to extract more value from your business data.

Assets

  • Dedicated project and Logstore

    • If you use an instance of Anti-DDoS Pro of the former version that resides in the Chinese mainland, Simple Log Service creates a project named ddos-pro-project-Alibaba Cloud account ID-cn-hangzhou and a dedicated Logstore named ddos-pro-logstore by default after you enable the log analysis feature.

    • If you use an instance of Anti-DDoS Pro of the former version that resides outside the Chinese mainland, Simple Log Service creates a project named ddos-pro-Alibaba Cloud account ID-ap-southeast-1 and a dedicated Logstore named ddos-pro-logstore by default after you enable the log analysis feature.

      Important
      • You can write only logs in Anti-DDoS Pro of the former version to the dedicated Logstore. No limits are imposed for features such as query, analysis, alerting, and consumption.

      • If you have enabled the pay-by-ingested-data billing mode, Simple Log Service creates a dedicated Logstore that uses the pay-by-ingested-data billing mode by default. If you want to switch the billing mode from pay-by-ingested-data to pay-by-feature, you can modify the configuration of the Logstore. For more information, see Modify the configuration of a Logstore.

  • Dedicated dashboards

    By default, Simple Log Service generates two dashboards after you enable the feature.

    Note

    We recommend that you do not make changes to the dedicated dashboards because the dashboards may be upgraded or updated at any time. You can create a custom dashboard to visualize query results. For more information, see Create a dashboard.
