LoggerProvider

Read onlyYes

FinalYes

Entry point for the logging API.

Creates and manages loggers for different instrumentation scopes. The behavior (void, memory, OTLP, etc.) is determined by the injected processor.

Example usage:

// For testing with memory storage
$processor = new MemoryProcessor($exporter, $exporter, $exporter);
$provider = new LoggerProvider($processor, new SystemClock());

// For OTLP export
$processor = batching_log_processor(otlp_log_exporter($transport));
$provider = new LoggerProvider($processor, new SystemClock());

// For void/disabled logging
$provider = new LoggerProvider(new VoidProcessor(), new SystemClock());

$logger = $provider->logger('my-service', '1.0.0');
$logger->info('Application started');

Methods

__construct() : mixed
logger() : Logger: Create a logger for the given instrumentation scope.

__construct()


    public
                    __construct(LogProcessor $processor, ClockInterface $clock, ContextStorage $contextStorage) : mixed

Parameters

$processor : LogProcessor
$clock : ClockInterface
$contextStorage : ContextStorage

logger()

Create a logger for the given instrumentation scope.


    public
                    logger(resource $resource, string $name[, string $version = 'unknown' ][, null|string $schemaUrl = null ][, null|Attributes $attributes = null ]) : Logger

Note: Instance caching is handled by the Telemetry class. This method always creates a new Logger instance.

Parameters

$resource : resource: The resource context for all logs from this logger
$name : string: The name of the instrumentation scope (e.g., library name)
$version : string = 'unknown': The version of the instrumentation scope
$schemaUrl : null|string = null: Schema URL for semantic conventions
$attributes : null|Attributes = null: Additional scope attributes

Return values
