You can look at our example project for how to trace a simple web application. For example, this includes trace filters for Servlet and log correlation for Apache Log4J. This repository includes dependency-free Java libraries and instrumentation for common components used in production services. While typically trace data is sent to Zipkin server, third-party plugins are available to send to alternate services such as Amazon X-Ray. Brave typically intercepts production requests to gather timing data,Ĭorrelate and propagate trace contexts. Brave is a distributed tracing instrumentation library.
