Abstract

A system (30) includes an analysis engine (34) and a notification engine (38) for selective notification of a condition (72) of an apparatus (26) monitored by a monitoring device (28). A method executed by the system (30) receives (116) data elements (58) from the monitoring device (28), processes (118) the data elements (58) to detect the condition (72) of the apparatus (26), and determines that the condition (72) defines an exception (74) to a normal condition (70) of the apparatus (26). A first notice (60) of the condition (72) is conveyed (146) to a responsible party (59) at a first instance of determination of the exception (74), and conveyance of a second notice (60) is prevented (140) at a second, subsequent, instance of determination of the exception (74). In addition, communication of the normal condition (70) of the apparatus (26) is prevented.
