OpenTelemetry

We hold regular meetings. See details at community page.

Overview

OpenTelemetry is a working name of a combined OpenCensus and OpenTracing project.

This project contains the following top level components:

api: The OpenTelemetry API.
- trace: The tracing api. Includes Tracer, Span and SpanContext.
- correlationcontext: Collection of entries in the form of key-value pairs of data that can be propagated to provide contextual information.
- context: In-process and inter-process propagation layer.
- metrics: Metrics layer.
sdk: The reference implementation complying to the OpenTelemetry API.
OpenTracing shim: A bridge layer from OpenTelemetry to the OpenTracing API.

We would love to hear from the larger community: please provide feedback proactively.

Snapshots

Snapshots based out the master branch are available for opentelemetry-api, opentelemetry-sdk and the rest of the artifacts:

    </dependency>
  </dependencies>

Gradle

repositories {
	maven { url 'https://oss.jfrog.org/artifactory/oss-snapshot-local' }
}

dependencies {
	compile('io.opentelemetry:opentelemetry-api:0.2.0-SNAPSHOT')
}

Libraries will usually only need opentelemetry-api, while applications may want to use opentelemetry-sdk.

Releases

OpenTelemetry Java is under active development. Releases aren't guaranteed to conform to a specific version of the specification. Future releases will not attempt to maintain backwards compatibility with previous releases.
