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 only for TencentDB for MySQL (excluding the Basic Edition).
Log in to the DBbrain Console, select Diagnosis and Optimization on the left sidebar, and select Health Report at the top. You can view the health score trends and the problem overview for the specified time period.
The time period of the health report is the same as that selected on the left.
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.
A report contains the following sections: overview, basic information, health, instance status, exception diagnosis, slow SQL analysis, big table analysis, and performance curve.
