How the BlackBerry Enterprise Server calculates health scores
Certain BlackBerry Enterprise Server components calculate a health score that indicates how well the component can provide specific services. The components send their health scores to the BlackBerry Dispatcher, which combines the health scores of the components to calculate the overall health score of the BlackBerry Enterprise Server. The BlackBerry Dispatcher writes the information to the BlackBerry Configuration Database, and it provides the information to a BlackBerry Enterprise Server that requests it.
