A system for remote monitoring of a machine is provided. The system includes a data store to store machine data associated with an operation of the machine. The system includes an analyzer comprising a plurality of analytics engines to analyze the machine data. The analyzer selects one or more analytics engines based at least on one of machine data and a type of the machine. The analyzer is further configured to analyze machine data using the selected one or more analytics engines and to determine a plurality of exceptions. The system includes a rules engine to process at least two of the plurality of exceptions and determine a smart exception, wherein the smart exception is a hierarchical combination of the at least two of the plurality of exceptions. The system includes an interface to display a notification to a user in the event of a smart exception.

System for analyzing machine data

A method, system, and apparatus to determine a malfunction or an abnormal pressure condition in a hydraulic system over a time period are provided. The method, system, and apparatus include monitoring hydraulic accumulator charge time, hydraulic accumulator discharge time, and hydraulic pump pressure over the time period, and determining whether the monitored hydraulic accumulator charge time, hydraulic accumulator discharge time, and hydraulic pump pressure are within respective predetermined ranges. A maintenance notification is output responsive to at least one of the monitored hydraulic accumulator charge time, hydraulic accumulator discharge time, and hydraulic pump pressure being outside the respective predetermined ranges during the time period.
