jmxtrans docker-compose 运行

以下是一个简单的demo,使用jmxtrans 进行jmx 指标的处理,项目使用docker-compose 运行
同时写入数据到graphite

环境准备

  • docker-compose文件
 
version: "3"
services: 
  graphite:
    image: graphiteapp/graphite-statsd
    ports:
    - "80:80"
    - "2003-2004:2003-2004"
    - "2023-2024:2023-2024"
    - "8125:8125/udp"
    - "8126:8126"
  jmxtrans:
    build: 
      context: ./
      dockerfile: Dockerfile-jmxtrans
  app:
    build: ./
    image: dalongrong/java-jmx-openjdk
    container_name: app
    ports: 
    - "8080:8080"
    - "30384:30384"
  • dockerfile 说明
    包含了一个spring boot 的项目app
    Dockerfile

        }]
      }
    ]
  }]
}

配置说明

  • jmx 服务app
    主要是通过运行的时候启动jmx 配置,具体可以参考docker-entrypiont.sh
  • jmxtrans
    通过docker 运行,主要是配置文件jmxtrans.json 添加了几个查询,同时通过GraphiteWriter
    写入数据到Graphite
    几个参数的说明,如果看了官方的wiki 以及代码就会发现,有几个参数是必须写的,但是wiki 不是很清楚
    主要是rootPrefix,flushStrategy,typeNames

启动&&测试

  • 启动
 
docker-compose up -d
  • 效果

 

说明

以上是一个简单的docker-compose 运行,实际上我们可以进行扩展,添加更多的jmx 指标,对于kuberntes 的运行方式,可以参考类似的方式,只是
我们可以使用localhost 在pod 中运行多个容器的方式解决,还是比较方便的
