Logger setting

Exometer depends on lager. To unify logging in a elixir project, you can use lagger_logger or logger_lager_backend

config :logger, :console,
  format: "$time $metadata[$level] $message\n",
  metadata: [:request_id, :application, :module, :function, :file, :line]

config :lager, :error_logger_redirect, false
config :lager, :error_logger_whitelist, [Logger.ErrorHandler]
config :lager, :crash_log, false
config :lager, :handlers, [{LagerLogger, [level: :info]}]
