Abstract: Computer systems have the ability to monitor their components and operations, generate events which indicate the occurrence of a monitored condition (e.g. out of paper, Joe Smith just signed on, disk utilization nearing capacity, etc.), and process these events in some manner. The present invention provides significant enhancements to the latter capability.The events of an event stream or streams are "filtered" into categories or groups of events. Once categorized, the invention associates an action or actions with the categorized event. The associated action can be logging the event, routing the event to the electronic address of a user, or sending the event to an application program for further processing.

Abstract: An apparatus for producing machine executable object code, a program listing and a listing of design documentation from a source code program consisting of a plurality of statements of implementation code including keywords and a plurality of statements of design documentation code wherein the design documentation code includes words corresponding to the keywords of the implementation code. The apparatus includes a processor for reading the source code program, a compiler for producing the machine executable object code from the implementation code, and the program listing. Furthermore, the apparatus includes an extractor that produces the design documentation by listing all of the design documentation code with the corresponding keywords in the order of appearance in the source program.
