1. A machine, the machine comprising:
a track link including:
a body comprising a cavity;
a strain measurement device located in the cavity and configured to generate strain data indicating an amount of strain experienced by a portion of the track link;
a wireless communication device; and
a component controller configured to:
determine an amount of wear, of the portion of the track link, based on the strain data;
generate wear information indicating the amount of wear; and
cause the wireless communication device to transmit the wear information; and
a machine controller configured to:
compare the amount of wear to a wear threshold that is based on historical data regarding an amount of wear of one or more other components at a time when the one or more other components were replaced, and
cause an adjustment of an operation of the machine based on the amount of wear satisfying the wear threshold.
