The C++ [OpenTelemetry](https://opentelemetry.io/) client.
## Project Status
| Signal | Status | Project |
| ------- | ---------------------- | ------------------------------------------------------------------------ |
| Traces | Public Release | N/A |
| Metrics | Development [1] | N/A |
| Logs | Experimental [2] | N/A |
* [1]: The development of the metrics API and SDK based on new stable
specification is ongoing. The timelines would be available in release
milestone. The earlier implementation (based on old specification) can be
included in build by setting `ENABLE_METRICS_PREVIEW` preprocessor macro,
and is included under `*/_metrics/*` directory. This would be eventually
removed once the ongoing implemetation is stable.
* [2]: The current Log Signal Implementation is Experimental, and will change as
the current OpenTelemetry Log specification matures. The current
implementation can be included in build by setting `ENABLE_LOGS_PREVIEW`
preprocessor macro.
## OpenTelemetry Specification Compatibility Matrix
| API Version | Core Version | Contrib Version |
| ----------- |--------------|-------------------------|
| 1.0.0 | 1.0.0-rc4 | N/A [1] |
| 1.0.0 | 1.0.0 | N/A |
* [1]: We don't have releases for opentelemetry-cpp contrib repo. This may
change in future.
## Supported C++ Versions
Code shipped from this repository generally supports the following versions of
C++ standards:
* ISO/IEC 14882:2011 (C++11, C++0x)
* ISO/IEC 14882:2014 (C++14, C++1y)
* ISO/IEC 14882:2017 (C++17, C++1z)
* 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-20.04 (Default GCC Compiler - 9.3.0) | CMake, Bazel |
| ubuntu-18.04 (GCC 4.8 with -std=c++11 flag) | CMake [1] |
| ubuntu-20.04 (Default GCC Compiler - 9.3.0 with -std=c++20 flags) | CMake, Bazel |
| macOS 10.15 (Xcode 12.2) | Bazel |
| Windows Server 2019 (Visual Studio Enterprise 2019) | CMake, Bazel |
[1]: Bazel build is disabled for GCC 4.8, as gRPC library 1.38 and above
(required by OTLP expoter) don't build with this compiler. See gRPC [official
support](https://grpc.io/docs/#official-support) document. CMake build doesn't
build OTLP exporter with GCC 4.8.
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).
## 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.
