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
Return values
mixed —__destruct()
public
__destruct() : mixed
Return values
mixed —close()
Closes the handler.
public
close() : mixed
This will be called automatically when the object is destroyed
Return values
mixed —getBubble()
Gets the bubbling behavior.
public
getBubble() : bool
Return values
bool —true means that this handler allows bubbling. false means that bubbling is not permitted.
getFormatter()
Gets the formatter.
public
getFormatter() : FormatterInterface
Return values
FormatterInterface —getHandler()
Return the nested handler
public
getHandler([array<string|int, mixed> $record = null ]) : HandlerInterface
If the handler was provided as a factory callable, this will trigger the handler's instantiation.
Parameters
- $record : array<string|int, mixed> = null
Return values
HandlerInterface —getLevel()
Gets minimum logging level at which this handler will be triggered.
public
getLevel() : int
Return values

Return values
mixed —handleBatch()
Handles a set of records at once.
public
handleBatch(array<string|int, mixed> $records) : mixed
Parameters
- $records : array<string|int, mixed>
-
The records to handle (an array of record arrays)
Return values
mixed —isHandling()
Checks whether the given record will be handled by this handler.
public
isHandling(array<string|int, mixed> $record) : bool
Parameters
- $record : array<string|int, mixed>
-
Partial log record containing only a level key
Return values
bool —popProcessor()
Removes the processor on top of the stack and returns it.
public
popProcessor() : callable
Return values
callable —pushProcessor()
Adds a processor in the stack.
public
