1. A method, comprising: measuring, using a server, performance data for a plurality of computing systems in network; determining, using the server, an event equation comprising a plurality of operands and one or more boolean operators from a graphical user interface, each of the plurality of operands being associated with (1) a performance metric, (2) a system component, and (3) a specified behavior of the performance metric for the system component, wherein the event equation is indicative of a series of performance characteristics that are symptomatic of an underlying performance problem on the network if they occur at the same time, and wherein each specified behavior is within a determined normal operation level of the performance metric; evaluating the event equation using the server, by: for each operand, automatically determining a boolean value for the operand by determining whether a monitored behavior of the performance metric for the system component matches the specified behavior; and evaluating the event equation comprising the determined operand values using the one or more boolean operators to diagnose a particular component on the network for which the performance data is being measured with the underlying performance problem; directing a notification to one or more different individuals, the one or more individuals selected based on the diagnosed underlying performance problem; and displaying the notification of the diagnosed performance problem.
