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 ``` Contributing ------------ [](#contributing) This repository is a read-only git subtree split.
