Sometimes when you are working with JSF you might need to understand what is happening beneath the covers. It could be because you think a component is misbehaving and you want to make sure that is the case before you file a bug. To facilitate this you can turn the logging up and in Mojarra there are several loggers that you can use.
The following is a non-exhaustive list:
So say you want to see what the Flow subsystem is doing, well then you would set the logging for it to FINEST.
javax.enterprise.resource.webcontainer.jsf.flow=FINEST
Note how your application server sets this depends on its implementation.
