If you are looking for an all-in-one, easy-to-install auto-instrumentation javaagent, see opentelemetry-java-instrumentation.
If you are looking for examples on how to use the OpenTelemetry API to write your own manual instrumentation, or how to set up the OpenTelemetry Java SDK, see Manual instrumentation. Fully-functional examples are available in opentelemetry-java-docs.

Would you like to get involved with the project? Read our contributing guide. We welcome contributions!
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

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
,Meter
, andBaggage
- semantic conventions Generated code for the OpenTelemetry semantic conventions.
- context api The OpenTelemetry Context implementation.
- 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.
This project publishes a lot of artifacts. The easiest way to see the most recent stable artifacts is to use the
opentelemetry-bom
. Unstable artifacts are referenced by
the opentelemetry-alpha-bom
.
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!
Published releases are available on maven central. We strongly recommend using our published BOM to keep all dependency versions in sync.

dependencies {
implementation platform("io.opentelemetry:opentelemetry-bom:1.10.0")
implementation('io.opentelemetry:opentelemetry-api')
}
Note that if you want to use any artifacts that have not fully stabilized yet (such as metrics), then you will need to add an entry for the Alpha BOM as well, e.g.
dependencies {
implementation platform("io.opentelemetry:opentelemetry-bom:1.10.0")
implementation platform('io.opentelemetry:opentelemetry-bom-alpha:1.10.0-alpha')
implementation('io.opentelemetry:opentelemetry-api')
implementation('io.opentelemetry:opentelemetry-api-metrics')
}
Snapshots based out the main
branch are available for opentelemetry-api
, opentelemetry-sdk
and the rest of the artifacts.
We strongly recommend using our published BOM to keep all dependency versions in sync.

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.
For opentelemetry-java developers that need to test the latest source code with another
project, composite builds can be used as an alternative to publishToMavenLocal
. This
requires some setup which is explained here.
See the VERSIONING.md document for our policies for releases and compatibility guarantees.
