The C++ OpenTelemetry client.
Stable across all 3 signals i.e. Logs, Metrics, and Traces.
See Spec Compliance Matrix to understand which portions of the specification has been implemented in this repo.
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 is not a goal of the current project.
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.

As an application owner or the library author, you can find the getting started guide and reference documentation on opentelemetry-cpp.readthedocs.io
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.
