DescribeSlowLogs - ApsaraDB RDS - Alibaba Cloud Documentation Center

Queries the statistics on slow query logs.

Operation description

Supported database engines

MySQL

Note This operation is not supported for RDS instances that run MySQL 5.7 on RDS Basic Edition.

SQL Server

Note This operation is supported only for RDS instances that run SQL Server 2008 R2.

MariaDB

Precautions

Slow query logs are not collected in real time and may show a latency of 6 to 8 hours.
If the return result is empty, check whether the StartTime and EndTime parameters are in UTC. If yes, no slow logs are generated within the specified time range.
Starting from December 13, 2023, the optimized template algorithm is used for slow queries. As a result, different SQLHash values are generated for the same SQLText before and after optimization. For more information, see [Notice] Optimization of the template algorithm for slow queries.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
