* Auto-instrumentation mechanism, **no need to CHANGE any application source code**. [Supported middlewares, frameworks and libraries](https://github.com/wu-sheng/sky-walking/wiki/3.1-supported-list).
* Explicit-instrumentation, as an [OpenTracing supported tracer](http://opentracing.io/documentation/pages/supported-tracers).
* Pure Java server implementation, with RESTful Web service.
* High performance streaming analysis.
* 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](#test-reports).
*[Supported middlewares, frameworks and libraries](https://github.com/wu-sheng/sky-walking/wiki/3.2-supported-list).
* Manual instrumentation
* As an [OpenTracing supported tracer](http://opentracing.io/documentation/pages/supported-tracers)
* 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](https://github.com/wu-sheng/sky-walking-ui)
