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 license

Abstract

  • An open source Large-Scale Distributed Systems Tracing Infrastructure, also known a ditributed tracer.
  • Based on Google Dapper Paper: Dapper, a Large-Scale Distributed Systems Tracing Infrastructure, Simplified Chines
  • Supports popular rpc frameworks, such as dubbo, dubbox, motan etc., supports email-alert when application occurs unexpected exception。
  • Execution time of creating span than 100μs.
  • By using byte-buddy (Thanks to raphw), plugins use dynamic byte code generation to avoid invasive codes. plugins API, execution time of blocking saving span must between 200μs and 300μs, including execution time of dynamic byte code.
  • By using DataCarrier, provide parallel high-throughput processing capability.
  • Provide trace log analysis and presentation capabilities, Reduce or avoid add-on functions development.

Supported components

  • web container
    • Tomcat7
    • Tomcat8
  • database
    • mysql
    • oracle
    • h2
    • easily extend to support sybase, sqlserver, jtds, db2, informix
  • rpc framework
    • dubbo (tested 2.5.3)
    • dubbox (tested 2.8.4-dubbo protocol, 2.8.4-rest protocol)
    • httpClient 4.x
    • motan (tested 0.1.2)
  • cache
    • jedix 2.x
  • java local method
    • config package name or class name (Recommend to use in dev or test enviroment. Will cost too many in product enviroment.)

v2.0-2016 Quick Start

部署第三方软件 / Required of third party softwares

  • JDK 1.7
  • zookeeper 3.4.6
  • mysql
  • redis-3.0.5

插件支持的JDK / Supported jdk version

  • 1.7以上版本 / support 1.7+

编译与部署 / Build and deploy

下载官方的agent / Download offical agent

Download

下载并设置授权文件 / Download auth file

  • 注册并登陆过skywalking-webui,创建应用。(一个用户代表一个逻辑集群,一个应用代表一个服务集群。如前后端应用应该设置两个应用,但归属一个用户)
  • # and login in skywalking-webui. Create application as needed.
  • 下载授权文件,放在在agent jar所在目录中
  • download auth file(*.auth), and copy the auth file to directory of the agent jar

在运行时环境中设置环境变量 / set environment variables

export SKYWALKING_RUN=true
  • 设置完成后,SkyWalking将随应用启动运行
  • After set env, SkyWalking will be working, when application startup.

使用-javaagent 并启动应用程序 / start application with -javaagent

  • 为应用程序添加启动参数
java -jar ...  -javaagent:/..ospath../skywalking-agent-x.x-Final.jar
  • Tomcat可以使用修改启动文件,配置-javaagent参数

在应用程序中显示traceid / How to find tid

  • 通过web应用的http调用入口,通过返回的header信息,找到此次调用的traceid。前提:此web应用的url,已经使用skywalking进行监控。

源代码说明

Recent RoadMap

  • [In the schedule] v2.1-2017

    • release a version following OpenTracing.io
    • provide bridge mode lib to integrate data of system and tracer
    • provide English doc as default. Also provide Chinese version on Gitbook or Wiki
    • support log framework(log4j, log4j2, logback) to output traceid in system log.
  • [Dev] v2.0-2016

    • 移除对于Hadoop,HBase的依赖,降低部署和运维难度
    • 使用内嵌式数据库,和分布式集群
    • 移除副本发送机制
    • 支持数据文件的时间分片,支持集群TB级别日志文件存储
    • 支持统计和高效的准实时统计汇总
    • 更多插件的支持
      • motan rpc framework (provided)
  • [Release] v1.0-Final

    • 客户端与服务端间使用扩展后的网络协议,前置的测试版本无法兼容,以提高服务端的稳定性和健壮性。(在内部使用过程中,发生因为安全扫描,导致服务端宕机)
    • 引入javaagent模式,无需修改任何代码,完成监控。
    • 所有插件将基于字节码技术实现,原有的配置文件模式将被移除。
  • [Release] v1.0 beta

    • 修复大量前置版本的BUG
    • 提供基于MR的分析能力,能够对调用链进行分析汇总,并形成调用链统计视图
  • [Release] v1.0 alpha2

    • 基于v1.0-alpha1的较稳定版本,在内部环境进行数月运行,修复大量影响服务端运行稳定性的问题。
    • v1.0-beta,将提供定时分析任务,部分分析页面展现功能。
    • 预计:后续版本将在插件模式上有较大改变,计划针对java api的拦截和第三方拦截提供更小侵入性的方法。配置和拦截模式会发生相应变化。具体模式,参考v1.0-beta发布时的说明。
