ganglia3.6.1+jmxtrans+strom-0.9.4集成

1、安裝ganglia參考之前的一篇博客（以下示例使用ganglia組播方式，單播方式大家自己嘗試）

http://chengyanbin.blog.51cto.com/3900113/1591373

2、安裝jmxtrans

http://chengyanbin.blog.51cto.com/3900113/1654754

3、安裝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、為jmxtrans增加兩個json文件

分別獲取nimbus和supervisor節(jié)點(diǎn)的jvm信息，以下文件僅列舉了部分參數(shù)，如果有需要可以增加queries中的數(shù)據(jù)，以監(jiān)控更多的參數(shù)，具體的MBean的參數(shù)，可以通過jconsole來查看

nimbus.json

supervisor.json

                    ]

            ],
            "numQueryThreads": 2
        }
    ]
}

兩個json文件一定要注意host是主機(jī)名，如果寫ip的話，在ganglia里同一個節(jié)點(diǎn)會有兩個顯示，看著有點(diǎn)別扭，大家都統(tǒng)一使用hostname就好.ganglia的gmnod和gmetad不需要重啟，用自動收集。

說明：

    修改json文件需要重新啟動jmxtrans,查看jmxtrans日志/var/log/jmxtrans/jmxtrans.log.

    service jmxtrans restart

下面來張ganglia的主界面，監(jiān)控兩個節(jié)點(diǎn)

上圖顯示不出來監(jiān)控指標(biāo)，就放下面來了，可以看到supervisor的監(jiān)控數(shù)據(jù)已經(jīng)收集到ganglia里了。

下圖搞了master節(jié)點(diǎn)的頁面，可以看到nimbus group的監(jiān)控數(shù)據(jù)已經(jīng)顯示，node1節(jié)點(diǎn)的supervisor group懶得上圖了，大家可以明白了，不明白的去面壁去
