Simple Log Service:ApplyConfigToMachineGroup

Last Updated:Jan 21, 2026

Applies a Logtail configuration to a machine group.

Operation description

  • The Host consists of the project name and the Simple Log Service endpoint. You must specify the project in the Host.

  • Create an AccessKey pair. For more information, see AccessKey pair.
    An AccessKey pair for an Alibaba Cloud account provides full access to all API operations. This poses a security risk. For security reasons, we recommend that you create and use a RAM user for API access or routine O&M. The RAM user must have the permissions to manage Simple Log Service resources. For more information, see Create and authorize a RAM user.

  • Identify the name and region of the project. For more information, see Manage projects.

  • Create a Logtail configuration and obtain its name. For more information, see CreateConfig.

  • Create a machine group and obtain its name. For more information, see CreateMachineGroup.

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.
