Only proper analysis and cross comparisons on a ground station would give you this info. Real time monitoring like they do on fixed wing has been talked about for years now but always dismissed due to the potential pitfalls. The crew already have enough to concentrate on, never mind hundreds of HUMS parameters to add to that.
Data link back to engineering control? They could analyze in real time without disturbing the cockpit.
