Systems and methods for multi-site performance monitoring of process control systems

A performance monitoring system enables users of computing devices 14 to easily view performance indicators for any of a number of different process control sites 10A-C. A computing device displays a graphical user interface (GUI) that enables a user to identity one or more process control sites he or she is interested in monitoring. The computing device communicates with one or more servers 105 associated with the process control site(s) to receive and display a set of performance indicators tailored to the selected process control sites and to the user's interests. In some instances, the user selects multiple sites and the system acts as an aggregator that selects, prioritizes, and/or categorizes (based on any of a number of different factors) performance indicators to be provided to the user for the multiple sites.
