Health Report

Last updated: 2020-11-16 10:46:48

    The health report feature can routinely perform health checks on database instances and output the corresponding health reports for the specified time period, helping you gain in-depth insights into the health, failures, and risks of the database instance and providing you with professional optimization suggestions.


    Currently, health report is supported for TencentDB for MySQL (excluding the Basic Edition) and TencentDB for CynosDB (compatible with MySQL).

    Creating a Health Report

    Log in to the DBbrain Console and select Performance Optimization on the left sidebar. On the displayed page, select a database at the top and select the Health Report tab. You can view the health score trends and the problem overview for the specified time period.

    • Click Create Health Report to create a task. After the task is completed, you can view or download the health report for the specified time period.


      The time period of the health report is the same as that selected on the left.

    Interpreting a Health Report

    A health report displays DBbrain's evaluation of the overall operation conditions of the selected database instance in the specified time period. Items in the report includes the database's existing problems, an analysis of existing problems, and corresponding suggestions, helping you gain a comprehensive understanding of the overall operation status of the selected instance and coordinate relevant personnel to troubleshoot issues.
