AWS::IoT::Dimension

Use the AWS::IoT::Dimension to limit the scope of a metric used in a security profile for AWS IoT Device Defender. For example, using a TOPIC_FILTER dimension, you can narrow down the scope of the metric to only MQTT topics where the name matches the pattern specified in the dimension. For API reference, see CreateDimension and for general information, see Scoping metrics in security profiles using dimensions.
