Abstract: Systems and methods for an online predictive diagnostic and prognostic maintenance system are disclosed. The systems and methods may be configured for use with networked gaming machines. The systems and methods may operate in real time and may detect and analyze data representing various indicators of machine performance or a current or future decrease in machine performance. The data may represent or be used to predict machine performance and risk of failure and to identify necessary or recommended repair, maintenance or other performance issues. In another embodiment systems and methods are disclosed for automated analysis of data regarding machine operation and generation of rules related to predicting the future performance, repair and maintenance needs of machines.
