Simple Log Service:TagResources

Last Updated:Jan 25, 2024

Creates and adds tags to a resource.

Usage notes

  • Host consists of a project name and a Simple Log Service endpoint. You must specify a project in Host.
  • An AccessKey pair is created and obtained. For more information, see AccessKey pair.

    The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in Simple Log Service is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. Make sure that the RAM user has the management permissions on Simple Log Service resources. For more information, see Create a RAM user and authorize the RAM user to access Simple Log Service.

  • The information that is required to query logs is obtained. The information includes the name of the project to which the logs belong and the region of the project. For more information, see Manage a project.
  • For more information, see Authorization rules. The following types of resources are supported: project, Logstore, dashboard, machine group, and Logtail configuration.

Authentication resources

The following table describes the authorization information that is required for this operation. You can add the information to the Action element of a RAM policy statement to grant a RAM user or a RAM role the permissions to call this operation.




The resource format varies with the resource type.







OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

This operation uses only common request headers and does not have operation-specific request headers. For more information, see Common request parameters.
