Overview

FIXME Path based

This very basic filter, observe a logger, and save all received leaves, without any formatting.

With this observer you save a sort of execution trace. After that you can apply to another logger the same message sequence.

You can also simply check that two results are equal, for that, just compare the sequence message.
