A system tag is defined by the system. You can only query system tags. System tags present data relationships in a standard manner. In some specific cases, you can use system tags to assist in processing your business. For example, a cluster is associated with an Elastic Compute Service (ECS) instance. In this case, the system automatically adds the ID of the cluster as a system tag to the ECS instance. This way, you can determine the attribution of the ECS instance based on the system tag.
