ganglia3.6.1+jmxtrans+strom-0.9.4集成-创新互联

1、安装ganglia参考之前的一篇博客（以下示例使用ganglia组播方式，单播方式大家自己尝试）

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

{     "servers": [         {          "host": "master",             "port": "12345",             "queries": [                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "nimbus",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:type=Memory",                     "resultAlias": "nimbus.heap",                     "attr": [                         "ObjectPendingFinalizationCount"                     ]                 },                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "nimbus",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:name=Copy,type=GarbageCollector",                     "resultAlias": "nimbus.gc",                     "attr": [                         "CollectionCount",                         "CollectionTime"                     ]                 },                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "nimbus",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:name=Code Cache,type=MemoryPool",                     "resultAlias": "nimbus.threads",                     "attr": [                         "CollectionUsageThreshold",                         "CollectionUsageThresholdCount",                         "UsageThreshold",                         "UsageThresholdCount"                     ]                 },                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "nimbus",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:type=Runtime",                     "resultAlias": "nimbus.runtime",                     "attr": [                         "StartTime",                         "Uptime"                     ]                 }             ],             "numQueryThreads": 2         }     ] }

supervisor.json

{     "servers": [         {          "host": "node1",             "port": "12346",             "queries": [                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "supervisor",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:type=Memory",                     "resultAlias": "supervisor.heap",                     "attr": [                         "ObjectPendingFinalizationCount"                     ]                 },                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "supervisor",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:name=Copy,type=GarbageCollector",                     "resultAlias": "supervisor.gc",                     "attr": [                         "CollectionCount",                         "CollectionTime"                     ]                 },                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "supervisor",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:name=Code Cache,type=MemoryPool",                     "resultAlias": "supervisor.threads",                     "attr": [                         "CollectionUsageThreshold",                         "CollectionUsageThresholdCount",                         "UsageThreshold",                         "UsageThresholdCount"                     ]                 },                 {                     "outputWriters": [                         {                             "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",                             "settings": {                                 "groupName": "supervisor",                                 "host": "239.2.11.71",                                 "port": "8649"                             }                         }                     ],                     "obj": "java.lang:type=Runtime",                     "resultAlias": "supervisor.runtime",                     "attr": [                         "StartTime",                         "Uptime"                     ]                 }             ],             "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
