Abstract: A performance-monitoring system is configured to determine whether a diminished performance of a computing system warrants prompt remedial action by generating a score indicative of various aspects of the computing system. In some examples, the performance-monitoring system identifies a change to a computing system comprising at least one server running two or more applications; runs one or more diagnostic tests on each of the two or more applications to collect additional performance data; determines, based on the additional performance data, a relative performance score for each of the two or more applications, wherein the relative performance score for a respective application indicates at least an effect of the change on an ability of a user to use the respective application to perform one or more user operations; determines that the performance score is less than a threshold score; and automatically reduces a rate of transaction requests sent to the server.
