DeduplicationHandler extends BufferHandler
in package

Simple handler wrapper that deduplicates log records across multiple requests

It also includes the BufferHandler functionality and will buffer all messages until the end of the request or flush() is called.

This works by storing all log records' messages above $deduplicationLevel to the file specified by $deduplicationStore. When further logs come in at the end of the request (or when flush() is called), all those above $deduplicationLevel are checked against the existing stored logs. If they match and the timestamps in the stored log is not older than $time seconds, the new log record is discarded. If no log record is new, the whole data set is discarded.

This is mainly useful in combination with Mail handlers or things like Slack or HipChat handlers that send messages to people, to avoid spamming with the same message over and over in case of a major component failure like a database server being down which makes all requests fail in the same way.

Methods

__construct()

public __construct(HandlerInterface $handler[, string $deduplicationStore = null ][, int $deduplicationLevel = Logger::ERROR ][, int $time = 60 ][, bool $bubble = true ]) : mixed
Parameters
$handler : HandlerInterface

Handler.

$deduplicationStore : string = null

The file/path where the deduplication log should be kept

$deduplicationLevel : int = Logger::ERROR

The minimum logging level for log records to be looked at for deduplication purposes

$time : int = 60

The period (in seconds) during which duplicate entries should be suppressed after a given log is sent through

$bubble : bool = true

Whether the messages that are handled can bubble up the stack or not

clear()

Clears the buffer without flushing any messages down to the wrapped handler.

public clear() : 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.

getLevel()

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

public getLevel() : int
Return values
int

handle()

Handles a record.

public handle(array<string|int, mixed> $record) : bool
Parameters
$record : array<string|int, mixed>

The record to handle

Return values
bool —

true means that this handler handled the record, and that bubbling is not permitted. false means the record was either not processed or that this handler allows bubbling.

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)

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 pushProcessor(mixed $callback) : self
Parameters
$callback : mixed
Return values
self

setBubble()

Sets the bubbling behavior.

public setBubble(bool $bubble) : self
Parameters
$bubble : bool

true means that this handler allows bubbling. false means that bubbling is not permitted.

Return values
self

setLevel()

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

public setLevel(int|string $level) : self
Parameters
$level : int|string

Level or level name

Return values
self

appendRecord()

private appendRecord(array<string|int, mixed> $record) : mixed
Parameters
$record : array<string|int, mixed>

isDuplicate()

private isDuplicate(array<string|int, mixed> $record) : mixed
Parameters
$record : array<string|int, mixed>
