* 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/OpenSkywalking/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.
