DescribeSlowLogHistogramAsync - Database Autonomy Service

Asynchronously retrieves the slow log trend data of an instance.

Operation description

Before you call this operation, make sure that you fully understand the billing methods and pricing of DAS.

The following prerequisites must be met to call this operation:

The instance must have DAS Enterprise Edition or the smart operations and maintenance (O&M) service enabled. The smart O&M service is not yet published.
Use the latest version of the Alibaba Cloud SDK or the DAS SDK.
When you use an SDK to call the DAS service, set the region to cn-shanghai.

This is an asynchronous operation. A complete result is not returned immediately. If the isFinish parameter in the response is false, wait 1 second and call the operation again. Repeat the call until the isFinish parameter is true, at which point the complete result is returned.

Try it now

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
