Cloud Config monitors the changes of resources under your account, tracks configuration changes, and evaluates configuration compliance in real time. You can manage the scope of resources to be monitored through simple configuration.

Monitoring scope

After Cloud Config is activated, the resource types supported by all services are automatically added to the monitoring scope by default.
  • If you select All Supported Resource Types, new resource types supported by Cloud Config are automatically added to the monitoring scope by default.
  • If you select Custom Resource Types, you can select resource types as needed and Cloud Config can only monitor the custom resource types.

Monitoring statuses

In Cloud Config, the monitoring statuses of resources are as follows:
  • Not monitored
    • If a resource type is in the monitoring scope, you can view the resources of the resource type in the resource list. If you remove a resource type from the monitoring scope, the resources of the resource type are removed from the resource list.
    • After you remove a resource type from the monitoring scope, Cloud Config stops recording configuration changes for the resources of this resource type. The existing records about configuration changes are not deleted.
  • Monitoring
    If you add a resource group that has been removed from the monitoring scope to the monitoring scope again, the resources of the resource type reappear in the resource list. Cloud Config records the configuration changes of the resources again, and the existing records about configuration changes can be viewed normally.
    Note Cloud Config does not record the configuration changes made to the resources when the resource type is not in the monitoring scope.
