Apparatus and associated methods relate to monitoring health of a hydraulic system. A method includes monitoring pressure within the system and determining when a potential fatigue condition may occur based on counting the number of times pressure in the system has exceeded the at least one threshold. In some embodiments, strain cycle data is calculated based on a time sequence of signals generated by a hydraulic fitting, which is indicative of strain of the hydraulic fitting. An output signal indicative of the fatigue condition determined is generated. In some embodiments, the strain data includes a number of strain cycles that the time sequence of signals crosses from below a strain threshold to above the strain threshold.
