The health report feature can routinely perform health checks on database instances and output the corresponding health reports for the specified time period, which helps you gain in-depth insights into the database instance health, failures, and potential risks and provides professional optimization suggestions for your reference.
Note:
Currently, health report is supported only for TencentDB for MySQL (excluding Basic single-node instances), TencentDB for Redis, TDSQL-C for MySQL and self-built MySQL databases.
Health report email push is not supported for self-built databases currently.
