1. A method of controlling a network of cooling systems, comprising:
receiving first measurements captured by sensors in a plurality of cooling devices, including sensors configured to measure vibration, temperature or electrical current during each cooling cycle of a corresponding cooling device at a frequency calculated to determine a fundamental frequency of the cooling cycle of a corresponding cooling device;
identifying a first feature of the first measurements that indicates (i) onset of failure of a first cooling device when the first feature comprises a failure pattern identified in measurements obtained by at least one sensor that is associated with the first cooling device, or (ii) instability in a component of the first cooling device;
initiating a service or repair procedure configured to prevent failure of the first cooling device;
receiving second measurements captured by the sensors in the plurality of cooling devices after the first cooling device has been repaired; and
determining whether a second feature present in the second measurements indicates that the first cooling device is operating at or above an optimal or nominal performance level, the second feature corresponding to a healthy pattern identified in the first measurements and the second measurements, wherein the healthy pattern is associated with one or more other cooling devices operating at or above the optimal or nominal performance level.
