The C++ [OpenTelemetry](https://opentelemetry.io/) client.

## Project Status

**Stable** across all 3 signals i.e. `Logs`, `Metrics`, and `Traces`.

See [Spec Compliance
Matrix](https://github.com/open-telemetry/opentelemetry-specification/blob/main/spec-compliance-matrix.md)
to understand which portions of the specification has been implemented in this
repo.

## Supported C++ Versions

Code shipped from this repository generally supports the following versions of
C++ standards:

* ISO/IEC 14882:2014 (C++14)
* ISO/IEC 14882:2017 (C++17)
* ISO/IEC 14882:2020 (C++20)

Any exceptions to this are noted in the individual `README.md` files.

Please note that supporting the [C Programming
Language](https://en.wikipedia.org/wiki/C_(programming_language)) is not a goal
of the current project.

## Supported Development Platforms

 Our CI pipeline builds and tests on following `x86-64` platforms:

| Platform                                                            |   Build type  |
|---------------------------------------------------------------------|---------------|
| ubuntu-22.04 (GCC 10, GCC 12, Clang 14)                             | CMake, Bazel  |
| ubuntu-20.04 (GCC 9.4.0 - default compiler)                         | CMake, Bazel  |
| ubuntu-20.04 (GCC 9.4.0 with -std=c++14/17/20 flags)                | CMake, Bazel  |
| macOS 12.7 (Xcode 14.2)                                             | Bazel         |
| Windows Server 2019 (Visual Studio Enterprise 2019)                 | CMake, Bazel  |
| Windows Server 2022 (Visual Studio Enterprise 2022)                 | CMake         |

In general, the code shipped from this repository should build on all platforms
having C++ compiler with [supported C++ standards](#supported-c-versions).

## Dependencies

Please refer to [Dependencies.md](docs/dependencies.md) for OSS Dependencies and
license requirements.

## Installation

Please refer to [INSTALL.md](./INSTALL.md).

### Bazel Central Registry

This project is available in the [Bazel Central Registry (BCR)](https://github.com/bazelbuild/bazel-central-registry/tree/main/modules/opentelemetry-cpp).
To use it with Bazel, add the following to your `MODULE.bazel` file:

```python
bazel_dep(name = "opentelemetry-cpp", version = "x.y.z")
```

For the latest version, see [BCR: opentelemetry-cpp](https://github.com/bazelbuild/bazel-central-registry/tree/main/modules/opentelemetry-cpp).

## Getting Started

As an application owner or the library author, you can find the getting started
guide and reference documentation on
[opentelemetry-cpp.readthedocs.io](https://opentelemetry-cpp.readthedocs.io/en/latest/)

The `examples/simple` directory contains a minimal program demonstrating how to
instrument a small library using a simple `processor` and console `exporter`,
along with build files for CMake and Bazel.
