SkyWalking: APM (application performance monitor) tool for distributed systems, especially designed for microservices, cloud native and container-based (Docker, K8s, Mesos) architectures. Underlying technology is a distributed tracing system.

• Provide Java agent, no need to CHANGE any application source code.
  • High performance agent. Only increase extra 10% cpu cost in 5000+ tps application, even when collect all traces.
  • 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.
• The UI released on skywalking-ui
