IoT / Client / create_dimension



Create a dimension that you can use to limit the scope of a metric used in a security profile for IoT Device Defender. For example, using a TOPIC_FILTER dimension, you can narrow down the scope of the metric only to MQTT topics whose name match the pattern specified in the dimension.
