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.
