1. A system comprising:

  • a plurality of sensors each disposed in or proximate to a reciprocating system, wherein each sensor is positioned to monitor at least one parameter related to the reciprocating system'"'"'s performance over time and to periodically measure values of the corresponding at least one parameter, each of the sensors measuring values of at least one of a plurality of parameters differing from a value measured by any other one of the sensors; and

    a data processing system configured toperiodically receive values for the parameters based upon measurements from the plurality of sensors,combine received values based upon measurements during a single measurement interval by different ones of the plurality of sensors;

    aggregate the combined values over a plurality of measurement intervals to compute a total energy number for at least one part of the reciprocating system; and

    compare a current computed value of the total energy number with a predictive failure value specific to a configuration for the reciprocating system.
