US Patent 7774790 Event logging and performance analysis system for applications

An event logging and analysis mechanism which creates an event object for event of an application to be logged. The event logging mechanism logs into the event object the start time, end time and other information regarding the event. The analysis of the collected event objects may include hierarchical and contextual grouping as well as aggregation of events considered to be identical. The mechanism operates independent of the application whose events it logs and can be turned on and off independently. A user may define the levels of hierarchy and contexts upon which to analyze the event objects.
