PassThroughMetricProcessor implements MetricProcessor

Read onlyYes

FinalYes

Exports each metric immediately when processed.

Unlike BatchingMetricProcessor, this processor exports metrics synchronously one at a time. This is useful for debugging and development where immediate visibility of metrics is more important than performance.

Example usage:

$processor = new PassThroughMetricProcessor($metricExporter);

Interfaces

MetricProcessor: Interface for processing metric measurements.

Methods

__construct() : mixed
exporter() : MetricExporter: Get the exporter used by this processor.
flush() : bool: Export all pending metrics.
process() : void: Process a metric measurement.

__construct()


    public
                    __construct(MetricExporter $exporter) : mixed

Parameters

$exporter : MetricExporter

exporter()

Get the exporter used by this processor.


    public
                    exporter() : MetricExporter

Return values

MetricExporter

flush()

Export all pending metrics.


    public
                    flush() : bool

Forces immediate export of any buffered metrics.

Return values

bool —

True if all metrics were successfully exported

process()

Process a metric measurement.


    public
                    process(Metric $metric) : void

This is invoked when an instrument records a value. The processor may buffer the metric, export it immediately, or discard it based on filtering rules.

Parameters

$metric : Metric
