logrus as its logger component.
These loggers can be tagged with attributes to make it easy to filter and find log messages.
Moleculer does that internaly, so the logger used in the registry is tagged
registry for example.

The logger that you can access from the context from within an action hanbdler is tagged with the action name :)
For the MVP we have not exposed much log configurations, options. Please let us know what your needs are and please also help us by submitting a PR wiht your ideas/suggestions.
We have plans to add plugins to connect moleculer logs with cloud loggins systems like papertrail.
