OpenTelemetry protobuf files

Protobuf Runtime library

OTLP exporting requires a protobuf runtime library.

There exist two protobuf runtime libraries that offer the same set of APIs, allowing developers to choose the one that best suits their needs.

This package requires google/protobuf, which is the native implementation. It is easy to install and a good way to get started quickly.

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

pecl install protobuf

The extension can be installed alongside the native library, and it will be used instead if available.
