DescribeSlowLogs - ApsaraDB RDS - Alibaba Cloud Documentation Center

You can call the DescribeSlowLogs operation to query the summary of the slow query logs of an ApsaraDB RDS instance.

Operation Description

Before you call this operation, make sure that the instance runs one of the following database engine versions:

All MySQL versions except MySQL 5.7 that is used with RDS Basic edition
SQL Server 2008 R2
MariaDB 10.3

NoteSlow query logs are not collected in real time and may show a latency of 6 hours to 8 hours.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
