OpenTelemetry OTLP exporter
===========================

[](#opentelemetry-otlp-exporter)

Documentation
-------------

[](#documentation)

Usage
-----

[](#usage)

See [https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/traces/exporters/otlp\_http.php](https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/traces/exporters/otlp_http.php)

Http transport
--------------

[](#http-transport)

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

gRPC transport
--------------

[](#grpc-transport)

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

Protobuf Runtime library
------------------------

[](#protobuf-runtime-library)

OTLP exporting requires a [protobuf implementation](https://github.com/protocolbuffers/protobuf/tree/main/php).

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
```
