The above events receive logging events from all the sub-groups
displayed below, and each event also reciving events from the event
above in importance.
The above events are not cascading, so add both ``errors'' and
``events'' to an output to receive both.
Thus some high-volume sub-group events such as ``tracker\_debug'' are
not part of ``debug'' and every ``warn'' event will receive events
from ``error'', ``critical''.
High-volume sub-group events such as ``tracker\_debug'' are not part
of ``debug\_trace''.
