一、JMX 简介

官网：Apache HBase ™ Reference Guide

JMX （Java管理扩展）提供了内置的工具，使您能够监视和管理Java VM。要启用远程系统的监视和管理，需要在启动Java VM时设置系统属性com.sun.management.jmxremote.port（希望通过该端口号启用JMX RMI连接）。

访问：

curl http://hdp-node2:16030/jmx?qry=Hadoop:service=HBase,name=RegionServer,sub=Server

输出的指标如下：

如上监控主要是HBase 内某个RegionServer 详细信息。具体有gc， scan，flush ，block,compaction 等细粒度的监控。

二、JMX监控信息钉钉告警实现

下面我们实现了一个RegionServer运行时长的钉钉通知消息
