OpenTelemetry OTLP exporter

Documentation

https://opentelemetry.io/docs/instrumentation/php/exporters/#otlp

Usage

See https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/traces/exporters/otlp_http.php

Http transport

$transport = (new \OpenTelemetry\Contrib\Otlp\OtlpHttpTransportFactory())->create('http://collector:4318', 'application/json');
$exporter = new \OpenTelemetry\Contrib\Otlp\SpanExporter($transport);

gRPC transport

To export over gRPC, you will need to additionally install the open-telemetry/transport-grpc package.

Protobuf Runtime library

OTLP exporting requires a protobuf implementation.

The open-telemetry/gen-otlp-protobuf requires the google/protobuf native implementation. It's fine for development, but not recommended for production usage.

The recommended option for production is to install the Protobuf C extension for PHP. The extension makes exporting significantly more performant. This can be easily installed with the following command:

pecl install protobuf
