Where to correctly store the functions that should be available in any controller?

Question

symfony

Good afternoon
I'm tormenting symfony 3, but she's me
I need to write something like a user action
logger That is - the user logged in - the logger wrote down The user
left = the logger wrote down The user
wrote a comment - the logger made a note again
Such user actions are scattered over several bundles, respectively, the logger should be available everywhere
Question - where and how can I write this logger?
Does it need a separate bundle?
Tell me at least how to google this question or in which direction to dig))

Move this same logger to a separate class with your own methods (functions)
