- Registry: The
Monolog\Registry
class lets you configure global loggers that you can then statically access from anywhere. It is not really a best practice but can help in some older codebases or for ease of use. - ErrorHandler: The
Monolog\ErrorHandler
class allows you to easily register a Logger instance as an exception handler, error handler or fatal error handler. - SignalHandler: The
Monolog\SignalHandler
class allows you to easily register a Logger instance as a POSIX signal handler. - ErrorLevelActivationStrategy: Activates a FingersCrossedHandler when a certain log level is reached.
- ChannelLevelActivationStrategy: Activates a FingersCrossedHandler when a certain log level is reached, depending on which channel received the log record.
