A method, apparatus, and system for controlling a device. A device control system comprises a computer system and a controller in the computer system. The controller receives internal sensor data for a group of internal parameters generated by an internal sensor system that senses the group of internal parameters within the device that relate to an operation of the device and receive external sensor data for a group of external parameters generated by an external sensor system that senses the group of external parameters in an environment around the device that relate to the operation of the device. The controller sends the internal sensor data and the external sensor data for an analysis with aggregated internal sensor data and aggregated external sensor data for devices of a same class as the device to generate results. The controller controls the operation of the device based on the results of the analysis.
