Abstract: A method utilizes a virtual flight recorder to harvest a subset of events being collected by an active system tracing facility during operation of a computer system. The virtual flight recorder is “virtual” from the sense that it is not specifically instrumented into a component with which the virtual flight recorder is associated, which eliminates the burden on developers to specifically instrument components of interest, and minimizes the impact on system performance as a result of performance metric collection.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment convert e-mail into physical mail. In various embodiments, if a recipient identifier in the e-mail is an e-mail address, the recipient identifier is retained. But, if the recipient identifier in the e-mail is not an e-mail address, the recipient identifier, or a street address associated with the recipient identifier, is printed on an envelope, and the e-mail is also printed. Postage may also optionally be printed on the envelope. In this way, persons who do not have an e-mail address may still receive the contents of e-mail via physical delivery.
