Sampling handler

A sampled event stream can be useful for logging high frequency events in
a production environment where you only need an idea of what is happening
and are not concerned with capturing every occurrence. Since the decision to
handle or not handle a particular event is determined randomly, the
resulting sampled log is not guaranteed to contain 1/N of the events that
occurred in the application, but based on the Law of large numbers, it will
tend to be close to this ratio with a large number of attempts.

public __construct( $handler, int $factor)
  • psalm-param HandlerInterface|callable(array, HandlerInterface): HandlerInterface $handler
public Monolog\Handler\Handler::__destruct()
public Monolog\Handler\Handler::__sleep()
public Monolog\Handler\Handler::close() : void


public Monolog\Handler\AbstractHandler::getBubble() : bool

Gets the bubbling behavior.

  • return bool true means that this handler allows bubbling. false means that bubbling is not permitted.
public getFormatter() : Monolog\Formatter\FormatterInterface


public getHandler(?array $record = NULL)

Return the nested handler

If the handler was provided as a factory callable, this will trigger the handler's instantiation.

public Monolog\Handler\AbstractHandler::getLevel() : int

Gets minimum logging level at which this handler will be triggered.

  • return int

  • suppress PhanTypeMismatchReturn
public Monolog\Handler\AbstractHandler::reset()
public Monolog\Handler\AbstractHandler::setBubble(bool $bubble) : self

Sets the bubbling behavior.

  • return self

public Monolog\Handler\AbstractHandler::setLevel( $level) : self

Sets minimum logging level at which this handler will be triggered.
