We are excited to introduce two new enhancements to AWS IoT Device Defender ML Detect, Custom Metrics and Dimensions support. ML Detect now supports monitoring of custom metrics, allowing you to evaluate operational health parameters that are unique to your fleet. Besides setting static alarms manually with Rules Detect, you can now use machine learning to automatically learn your fleet’s expected behaviors on custom metrics. Further, with the new Dimensions filter support for ML Detect, you can define attributes to evaluate more precise metrics in your ML security profile.
