1. A system, comprising:
a hose assembly configured to be connected to a hydraulic circuit of a machine,
wherein a first layer, of a hose of the hose assembly, is configured to transport a hydraulic fluid,
wherein a second layer, of the hose, comprises a tracer material that is configured to be released into the hydraulic fluid when the first layer is experiencing a failure;
a sensor device configured to:
detect the tracer material in the hydraulic fluid, and
generate sensor data indicating that the tracer material has been detected; and
a controller configured to:
determine that the hose assembly is experiencing the failure based on the sensor data; and
cause an action to be performed based on determining that the hose assembly is experiencing the failure.
