 SkyWalking: Large-Scale Distributed Systems Tracing Infrastructure, 是一个对JAVA分布式应用程序集群的业务运行情况进行追踪、告警和分析的系统。
 
+[![Build Status](https://travis-ci.org/wu-sheng/sky-walking.svg?branch=master)](https://travis-ci.org/wu-sheng/sky-walking)
 
 * 核心理论为[Google Dapper论文：Dapper, a Large-Scale Distributed Systems Tracing Infrastructure](http://research.google.com/pubs/pub36356.html),英语有困难的同学可参考[国内翻译](http://duanple.blog.163.com/blog/static/70971767201329113141336/)
 * 本分析系统能通过不修改或少量修改代码的模式，对现有的JAVA应用或J2EE应用进行监控和数据收集，并针对应用进场进行准实时告警。此外提供大量的调用性能分析功能，解决目前的监控系统主要监控进程、端口而非应用实际性能的问题。
