Cubic是什么

Cubic 一站式问题定位平台,以agent的方式无侵入接入应用,提供各种指标,动态线程堆栈追踪,完整集成arthas功能模块,致力于应用级监控,帮助开发人员快速定位问题。

官方网站:https://cubic.jiagoujishu.com

Gitee: https://gitee.com/dromara/cubic

Github: https://github.com/dromara/cubic

Demo: http://43.138.50.220:6080

特性:

  • 1、兼容性:整体监控不管你是IDC、ECS、Docker部署,都可完美兼容
  • 2、易用: 无需任何配置,开箱即用,基于agent无侵入接入,升级应用端无感知
  • 3、强大: 支持对应用的基础监控、堆栈监控、线程池监控等等
  • 4、高扩展:提供良好的扩展接口,给你自主选择

开发环境部署

只需两步:

  • 执行cubic-proxy -> resources -> db -> init.sql 创建表
  • 执行运行脚本 build-start.sh 打包部署应用

如有问题?

请看Q/A章节y

文档

结构

cubic-agent 应用数据采集agent
config 存放agent配置文件
cubic-proxy 代理应用,用于接收agent数据
cubic-proxy-common 公共基础参数
cubic-proxy-websocket 代理应用,用于接收页面与proxy之间的数据通信
cubic-ui 页面UI,提供前端各种功能展示,打包完 将dist目录数据拷贝到cubic-proxy
docs 文档
scripts 包含打包脚本、启动脚本
agent-dist 存放打包后的agent完整组件
agent-proxy-dist 存放打包后 proxy 部署 jar
arthas-dist 用于支持arthas命令集

技术体系:

  • 基于最新Spring Boot 整体技术栈
  • 认证模块是基于Spring Boot Security JWT 技术
  • WebShell 基于 Vue Xterm 、Websocket、Netty 技术
  • Proxy 与 agent 通信基于Netty 、GRPC

Q&A

1、Q : 为什么页面迭代这么慢?

A : 因为目前自己抽时间在写,所以前端UI 有些小BUG ,功能、部署、脚本等等都在完善中,马上准备使用最新的VUE 那一套来进行页面的输出迭代了,欢迎各位大牛贡献代码。

2、Q : 为什么最近几个月未更新?

A : 因为换工作等问题导致的,后面会严格按照每月一个大版本进行更新

3、Q : 编译后protobuf文件找不到?

A : 重新执行下 mvn compile

4、Q : 环境依赖

A : JDK 1.8、 MySQL 5.5+

5、 Q : 报JDK版本错误或tools.jar不存在问题

A : cubic使用的java为JAVA_HOME/bin/java, 需要JDK8及以上,但"不要求"与目标应用的JVM使用相同的JDK版本。

cubic需要依赖JAVA_HOME/lib/tools.jar

JAVA_HOME的定位,通过读取环境变量JAVA_HOME,如果没有定义,则尝试通过"which java"定位java从而获得相对路径。

可通过echo $JAVA_HOME 查看当前配置

6、Q : 如果linux 上出现java.lang.NoClassDefFoundError: com/sun/tools/attach/VirtualMachine

A: 此时echo $JAVA_HOME 发现也已经配置,请在应用启动参数上增加 -Xbootclasspath/a:$JAVA_HOME/lib/tools.jar

**7、Q : 下载后有些编译报错 **

A: 不要怕,可以使用scripts里面的build.sh打包下即可。如果还有报错,点下IDEA的build(绿锤子)
