A system and method for generating a performance tool includes a builder, a seeker, and a catalyst. The builder is used to generate the seeker. The seeker is selected for operation, thereby launching the catalyst. The catalyst runs the seeker and receives assertions, such as selected answers, in response to interrogatives, such as questions. When all assertions are provided to all interrogatives, the seeker generates a yield. However, the yield also can be generated dynamically as the seeker operates.

Some embodiments provide application performance management tools with a service monitor that operates on a number of different mobile devices to track and monitor services that an application is using. In some embodiments, the service monitor stores a log relating to the use of the service each time the application uses the service. The application performance tool also includes an error monitor to detect an application error and report the application error to a performance monitoring server along with one or more logs relating to the use of the service when the error is detected. The performance monitoring server then provides an error report with the one or more logs to assist a developer in diagnosing the cause of the error with the application.

A method for application performance data collection includes steps or acts of: customizing a performance tool for collecting application performance data of an application; modifying the application by inserting the performance tool while the application does not need to be rebuilt from the source; executing the application; and collecting the application execution performance data such that only interesting data is collected.

A method and apparatus for monitoring electronic commerce transactions. A network delay agent, coupled to the access point for the electronic commerce provider's system is operable to send and receive communications to a designated customer's site for measuring network transport latency. Application test latency is also determined. An application monitor agent that is coupled to the electronic commerce provider's access point sends application tests that correspond to tasks performed during a typical electronic commerce transaction, to the electronic commerce provider's system. The time required for the electronic commerce provider's system to perform the indicated tasks and return a response to the application monitor agent is recorded as application test latency. Network transport latency and application test latency are displayed to indicate the delays that are experienced by a user in executing an electronic commerce order.

Processes for high speed machining of workpiece materials using high performance tools with prolonged tool life and improved surface finish are provided by vibrating the tool and / or the workpiece at a frequency greater than the frequency of shear localization in the primary shear zone or chip segmentation occurring in the absence of tool vibration, with an amplitude sufficient to break up the tool-chip atomic contact, thereby decreasing the tool-chip contact length through decreasing the tool-chip contact time, thereby suppressing accelerated chemical tool wear caused by dissolution of the tool into the workpiece by nanocrystalline grain boundary diffusion and grain boundary sliding mechanisms by preventing shear localization associated with nanocrystalline grain formation in the primary shear zone of the chip, and suppressing oxidation wear of the tool by preventing segmentation of the chip.

A shaping tool (10, 110) includes a cooling system (12) having one or more cooling passages (26, 126) configured for enhanced cooling. The cooling passages provide latent heat cooling of a heated material that is in contact with a shaping surface (24, 124) of the tool. Cooling fluid flows along the cooling passages in a two-phase flow regime in which a portion of the cooling fluid is liquid and a portion of the cooling fluid is vapor. A two-phase portion (28, 128) of the cooling passage can be shaped to follow a three-dimensional contour of the shaping surface. Opposing walls of the cooling passage can be provided by passage surfaces (42, 44, 142, 144) of separately formed pieces of the tool. The latent heat cooling provided by suitably configured cooling channels extracts more heat from the material being shaped in the tool than traditional cooling systems.
