## About this project

This is a repository for OpenTelemetry Erlang & Elixir contributions that are not part of the
[core repository](https://github.com/open-telemetry/opentelemetry-erlang) and
core distribution of the API and SDK.

## Instrumentations

OpenTelemetry can collect tracing data using instrumentation. Vendors/Users can also create and use their own. Currently, OpenTelemetry supports automatic tracing for:

- [opentelemetry-cowboy](https://github.com/open-telemetry/opentelemetry-erlang-contrib/tree/main/instrumentation/opentelemetry_cowboy)
- [opentelemetry-phoenix](https://github.com/open-telemetry/opentelemetry-erlang-contrib/tree/main/instrumentation/opentelemetry_phoenix)

## Supported Runtimes

OpenTelemetry requires OTP v21.3 and above.

See [Elixir OTP Compatability](https://hexdocs.pm/elixir/1.12/compatibility-and-deprecations.html#compatibility-between-elixir-and-erlang-otp) for supported OTP/Elixir combinations.
