No need of Hadoop, HBase, or Cassandra Cluster. * Pure Java server implements. provide gRPC (since 2.0) and HTTP (since 2.1) cross-platform spans collecting service. # Supported components ### web container * Tomcat 7 * Tomcat 8 [![Tomcat 7 Test Docker](https://img.shields.io/badge/test--scenario-tomcat--7.0.73-brightgreen.svg)](https://hub.docker.com/r/skywalking/docker-tomcat-scenario/tags/) [![Tomcat 8 Test Docker](https://img.shields.io/badge/test--scenario-tomcat--8.0.39-brightgreen.svg)](https://hub.docker.com/r/skywalking/docker-tomcat-scenario/tags/) ### database * mysql * oracle * h2 * easily extend to support sybase, sqlserver, jtds, db2, informix [![MySQL Test Docker](https://img.shields.io/badge/test--scenario-mysql--5.7-brightgreen.svg)](https://hub.docker.com/r/skywalking/docker-mysql-scenario/tags/)

Required of third party softwares - JDK 1.6+ ( instruments applications can run in jdk6 ) - JDK 1.8 ( skywalking servers ) - zookeeper 3.4.6 - mysql - redis-3.0.5 ## 2. Download and deploy servers - Download Server release version. [Download](https://github.com/wu-sheng/sky-walking/releases) (.tar.gz) ### 2.1 Run all servers in a Docker - Docker version include all-in-one servers. - Suitable for quick-look or test env. High performance and Scalable are not your requirements. ### 2.2 Deploy your own cluster - waiting for release. ## 3. Download agent [ ![Download](https://api.bintray.com/packages/wu-sheng/skywalking/com.a.eye.skywalking-agent/images/download.svg) ](https://bintray.com/wu-sheng/skywalking/com.a.eye.skywalking-agent/_latestVersion) ## 4. Create users, applications and alarm rules in webui - create user, remember your username. - create applications under the user, remember your application code. - create alarm rules for each applications. ## 4. Start application with -javaagent ```shell java -jar ... -javaagent:/..ospath../skywalking-agent-x.x.jar -Dusername=x -DapplicationCode=y -Dservers=192.168.1.16:3300,192.168.1.17:3300 ``` ## 5. Aha, your applications are being instrumented # 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 * not dependency on Hadoop or HBase, easy to deploy or maintenance * support simple-cluster mode * support docker mode in single-server-instance * support more plugins * motan rpc framework (provided)
