SkyWalking 3: APM for Distributed Systems, also known Distributed Tracing System.

• Auto instrumentation by javaagent, no need to CHANGE any application source code.
  • High performance agent. Only increase extra 10% cpu cost in 5000+ tps application, even do not need to use sampling mechanism, check test reports.
  • Supported middlewares, frameworks and libraries.
• Manual instrumentation
  • As an OpenTracing supported tracer
  • Use @Trace annotation for any methods you want to trace.
  • Integrate traceId into logs for log4j, log4j2 and logback.
• Pure Java server implementation, provide RESTful and gRPC services. Compatibility with other language agents/SDKs.
  • How to uplink metrics and traces to collector?
• The UI released on wu-sheng/sky-walking-ui
