Apache SkyWalking | [English](README.md)
==========
**SkyWalking**: 针对分布式系统的APM(应用性能监控)系统,特别针对微服务、cloud native和容器化(Docker, K8s, Mesos)架构,
其核心是个分布式追踪系统。

* Java自动探针,**不需要修改应用程序源代码**
* 高性能探针,针对单实例5000tps的应用,在**全量采集的情况下**,只增加**10%**的CPU开销。
* [中间件,框架与类库支持列表](docs/Supported-list.md).
* 手动探针
* [使用OpenTracing手动探针API](http://opentracing.io/documentation/pages/supported-tracers)
* 使用 [**@Trace**](docs/cn/Application-toolkit-trace-CN.md) 标注追踪业务方法
* 将 traceId 集成到 log4j, log4j2 或 logback这些日志组件中
* 纯Java后端Collector实现,提供RESTful和gRPC接口。兼容接受其他语言探针发送数据
* [如何将探针的Metric和Trace数据上传到Collector?](/docs/cn/How-to-communicate-with-the-collector-CN.md)
* UI工程请查看 [skywalking-ui](https://github.com/apache/incubator-skywalking-ui)
