Dear users,
Starting August 1, 2024, Alibaba Cloud [Security Center] upgrades log dictionaries to V2.0 to ensure consistent data analysis experience when you use Alibaba Cloud security services. The following items are involved in the upgrade:

Experience for new users is improved. Starting August 1, 2024, V2.0 log dictionaries are automatically applied when you create Logstores. This helps provide consistent log processing capabilities.

Experience for existing users is improved. If you already created Logstores, V2.0 log dictionaries are automatically applied to record the fields of new logs on October 30, 2024. This ensures data integrity and business continuity. The upgrade does not affect data in storage and ensures the integrity and availability of historical data.

Alibaba Cloud provides comprehensive documentation to answer questions you may have. If you encounter issues or need assistance during the upgrade, submit a ticket or call the service hotline of Alibaba Cloud.
