SamplingHandler
extends AbstractHandler
in package
implements
ProcessableHandlerInterface, FormattableHandlerInterface
Uses
ProcessableHandlerTrait
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.

Methods
__construct()
public
__construct(callable|HandlerInterface $handler, int $factor) : mixed
Parameters
- $handler : callable|HandlerInterface
-
Handler or factory callable($record|null, $samplingHandler).
- $factor : int
-
Sample factor (e.g. 10 means every ~10th record is sampled)
