A method includes determining, based on sensor data, that one or more components of substrate processing equipment are within a pre-failure window that is after a normal operation window. Corresponding data points in the normal operation window are substantially stable along a first health index value. The corresponding data points in the pre-failure window increase from the first health index value to a peak at a second health index value. Responsive to the determining that the one or more components are within the pre-failure window, the method further includes causing performance of a corrective action associated with the one or more components of the substrate processing equipment.
