Brave is a distributed tracing instrumentation library. Brave typically intercepts production requests to gather timing data, correlate and propagate trace contexts. While typically trace data is sent to Zipkin server, third-party plugins are available to send to alternate services such as Amazon X-Ray. This repository includes dependency-free Java libraries and instrumentation for common components used in production services. For example, this includes trace filters for Servlet and log correlation for Apache Log4J. Brave's dependency-free tracer library works against JRE6+. This is the underlying api that instrumentation use to time operations and add tags that describe them. This library also includes code that parses X-B3-TraceId headers.
Features
- All Brave libraries match the minimum Java version of what's being traced or integrated with, and adds no 3rd party dependencies
- All artifacts publish to the group ID "io.zipkin.brave". We use a common release version for all components
- Snapshots are uploaded to Sonatype which synchronizes with Maven Central
- When using multiple brave components, you'll want to align versions in one place. This allows you to more safely upgrade, with less worry about conflicts
- You can use our Maven instrumentation BOM (Bill of Materials)
- Brave typically intercepts production requests to gather timing data, correlate and propagate trace contexts
