If you are looking for an all-in-one, easy-to-install auto-instrumentation javaagent, please visit our sibling project, opentelemetry-java-instrumentation.
If you are looking for examples on how to use the OpenTelemetry APIs to write your own manual instrumentation, or how to set up the OpenTelemetry Java SDK, please visit our quickstart guide. We also have fully-functioning example projects in our examples sub-module, which can be a good way to get your feet wet in a local environment.
If you are looking to get involved with the project, please read our contributing guide. We welcome contributions!
If you are looking for a general overview of the OpenTelemetry project, please visit the official website.
We hold regular meetings. See details at community page.
We use GitHub Discussions for support or general questions. Feel free to drop us a line.
We are also present in the #otel-java channel in the CNCF slack.
Please join us for more informal discussions.
OpenTelemetry is the merging of OpenCensus and OpenTracing into a single project.
This project contains the following top level components:
- OpenTelemetry API:
- stable apis including
Tracer,Span,SpanContext, andBaggage - semantic conventions Generated code for the OpenTelemetry semantic conventions.
- context api The OpenTelmetry Context implementation.
- metrics api alpha code for the metrics API.
- stable apis including
- extensions define additional API extensions, which are not part of the core API.
- sdk defines the implementation of the OpenTelemetry API.
- sdk-extensions defines additional SDK extensions, which are not part of the core SDK.
- OpenTracing shim defines a bridge layer from OpenTracing to the OpenTelemetry API.
- OpenCensus shim defines a bridge layer from OpenCensus to the OpenTelemetry API.
- examples on how to use the APIs, SDK, and standard exporters.
We would love to hear from the larger community: please provide feedback proactively.
Unless otherwise noted, all published artifacts support Java 8 or higher. See CONTRIBUTING.md for additional instructions for building this project for development.
Both API and SDK extensions consist of various additional components which are excluded from the core artifacts to keep them from growing too large.
We still aim to provide the same level of quality and guarantee for them as for the core components. Please don't hesitate to use them if you find them useful.
Please refer to the contribution guide on how to set up for development and contribute!

}Libraries will usually only need opentelemetry-api, while applications
will want to use the opentelemetry-sdk module which contains our standard implementation
of the APIs.
