logging-facade
A logging API for Haskell, inspired by
slf4j. Code that logs messages with
logging-facade doesn't have to depend on or make any decisions about the
logging backend that you want to use in the end. Choosing the logging backend

executable. Only at that point you have to actually depend on the libraries that
you need for whatever logging backend you're going for.
logging-facade itself only depends on libraries that ship with ghc.
logging-facade has a sensible default: logging to stderr. And there are
back ends for both syslog
and journald:
