2、安装jmxtrans

3、安装storm
http://chengyanbin.blog.51cto.com/3900113/1654757
4、修改storm配置文件storm..yaml
###nimbus config nimbus.childopts: "-verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=12345 -Xmx1024m" ###supervisor config supervisor.childopts: "-verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=12346 -Xmx256m"
5、为jmxtrans增加两个json文件
分别获取nimbus和supervisor节点的jvm信息，以下文件仅列举了部分参数，如果有需要可以增加queries中的数据，以监控更多的参数，具体的MBean的参数，可以通过jconsole来查看
nimbus.json

"resultAlias": "supervisor.runtime",

"StartTime",

]
}
],
"numQueryThreads": 2
}
]
}两个json文件一定要注意host是主机名，如果写ip的话，在ganglia里同一个节点会有两个显示，看着有点别扭，大家都统一使用hostname就好.ganglia的gmnod和gmetad不需要重启，用自动收集。
说明：
修改json文件需要重新启动jmxtrans,查看jmxtrans日志/var/log/jmxtrans/jmxtrans.log.
service jmxtrans restart
下面来张ganglia的主界面，监控两个节点
上图显示不出来监控指标，就放下面来了，可以看到supervisor的监控数据已经收集到ganglia里了。
下图搞了master节点的页面，可以看到nimbus group的监控数据已经显示，node1节点的supervisor group懒得上图了，大家可以明白了，不明白的去面壁去
新闻名称：ganglia3.6.1+jmxtrans+strom-0.9.4集成
