Queries a list of machines that are connected to Simple Log Service in a machine group.
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.
