The invention relates to a method and device for monitoring the production of a knitting machine, and the knitting machine; the method for monitoring the production of a knitting machine is provided; wire supply of at least one wire supply device is monitored by a sensor device (19) and a control unit (20); a sensor signal (S) with a measuring pulse (I) for each length unit (delta XF) of a wire supply path is generated by the sensor device (19) in such condition. The sensor signal (S) is evaluated by the control unit (20); in a suitable condition, the control unit (20) is used for generating a stop signal (ST) for the knitting machine; a clock signal (S2) aiming at the control unit (20) is provided by a clock unit; a clock pulse (T) of the clock signal (S2) is matched with the length unit (delta XS) of a knitting path; the length unit (delta XS) of the knitting path is one/Zth of the length unit (delta XF) of the wire supply path (wherein the factor Z is at least 2, preferably 3-10); the sensor signal (S) is evaluated by the control unit (20), and depends on the generation of the clock signal (S2).
