US Patent 7895605 Method for tracking an event through multiple module-specific files

A method and apparatus for tracking data associated with an event across multiple files includes generating a particular value upon occurrence of a particular event during a first process spawned from a first module. The particular value is unique among all events during processes spawned from all modules. First data associated with the particular event is written to a first file of the multiple files. The first file records information associated with the first process according to the first module. The first data includes the particular value. Second data is sent to a second process spawned from a second module. The second data includes the particular value.
