Experiment

An experiment consists in an arbitrary number of aggregated LTTng traces. In the degenerate case, an experiment can consist of a single trace.

The experiment provides a unified, time-ordered stream of the individual LTTng trace events.

Since the individual traces are likely to have unsynchronized clocks (or at least skewed with respect to each other), the experiment supports a timestamp adjustment scheme that synchronizes all the events against a common reference clock. This simplifies events correlation between traces.
