Simple Log Service:CreateConfig

Last Updated:Feb 04, 2024

Creates a Logtail configuration.

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, the region of the project, and the name of the Logstore to which the logs belong. For more information, see Manage a project.
  • You can create up to 100 Logtail configurations in a project.
  • The Logtail configuration is planned out. For more information, see Logtail configurations.


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.
