1. A system for operating a machine at a work site, comprising;
- a prime mover;
a ground-engaging drive mechanism operatively connected to the prime mover to propel the machine about the work site;
a plurality of sensors associated with the machine for generating signals indicative of operating conditions of the machine; and
a controller configured to;
store a plurality of performance thresholds of the machine;
establish a path for the machine;
autonomously generate propulsion commands to propel the machine along the path in an autonomous or semi-autonomous manner;
receive a plurality of signals from the plurality of sensors;
determine a plurality of performance characteristics of the machine based upon the plurality of signals;
determine whether the plurality of performance characteristics meet the plurality of performance thresholds;
generate an alert command if any of the plurality of performance characteristics do not meet the plurality of performance thresholds; and
terminate the autonomous generation of propulsion commands to propel the machine along the path in an autonomous or semi-autonomous manner upon receipt of instructions from an operator to operate the machine manually.

Abstract
A system for monitoring a machine at a work site includes a prime mover, a ground-engaging drive mechanism to propel the machine, and a plurality of sensors. A controller generates propulsion commands to propel the machine about the work site in an autonomous or semi-autonomous manner and determines a plurality of performance characteristics of the machine. The controller further determines whether the plurality of performance characteristics meet a plurality of performance thresholds and generates an alert command if any of the plurality of performance characteristics do not meet the plurality of performance thresholds.
