Simple Log Service:GetCursorTime

Last Updated:Oct 26, 2023

Queries the time when a cursor is created on Simple Log Service.

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 pairs.

    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, the region of the project, and the name of the Logstore to which the logs belong. For more information, see Manage a project and Manage a Logstore.

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.
