使用telegraf 可以很好的采集相关的所有数据，而且是非入侵式

基本主流的应用都能采，插件式的

分为input 和 output 插件
平台说明
input 使用 jolokia telegraf 工具提供jolokia相关插件去获取activemq自带的api暴露的指标信息
output 我用的是prometheus client0，这是一个Prometheus客户端，会建立一个自己的socket。

部署在被采集机器

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.12.0-1.x86_64.rpm&& yum install -y telegraf-1.12.0-1.x86_64.rpm

  1. curl -u <你的用户>:<你的密码> http://127.0.0.1:8161/api/jolokia/
  2. 和mq控制台的用户密码信息一样

修改 /etc/telegraf/telegraf.conf

添加相关数据源，修改下实际的指标就能使用

会写一下怎么调试和新增jolokia的指标
