Overview

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

This project contains the following top level components:

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

Note about extensions

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.

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.
