1. A system, associated with an autonomous machine, for logging visual data and sensor data associated with a triggering event, comprising:

  • a camera disposed on the autonomous machine to provide visual data output of an area around the autonomous machine;

    a first sensor disposed on the autonomous machine to provide operational parameter output;

    a memory buffer to store the visual data output and the operational parameter output of the autonomous machine;

    an electronic map;

    a permanent memory device to selectively store contents of the memory buffer; and

    a controller configured to;

    identify, in the visual data output from the camera, objects in the area around the autonomous machine;

    compare the identified objects in the area around the autonomous machine to the electronic map;

    determine, based on the comparison, whether there is an inconsistency between the identified objects in the area around the autonomous machine and the electronic map;

    detect the triggering event on the autonomous machine based on a determination that there is an inconsistency between the identified objects in the area around the autonomous machine and the electronic map; and

    store, responsive to detecting the triggering event, the contents of the memory buffer in the permanent memory at a predetermined time after the triggering event, the contents corresponding to the visual data output and the operational parameter output occurring before, during, and after the triggering event.
