我正试图用jmxtrans和ganglia监视一个Kafka经纪人。但是使用下面的json，没有创建rrd。

打印在jmxtrans.log中的日志是 [01 Sep 2015 11:53:28] [SIGTERM handler] 4030449 DEBUG (com.googlecode.jmxtrans.JmxTransformer:463) - Stopped writer: GangliaWriter for query: Query [obj="kafka.network":type="RequestMetrics",name="Produce-RequestsPerSec", resultAlias=produce, attr=[Count, OneMinuteRate]] [01 Sep 2015 11:54:33] [main] 0 DEBUG (com.googlecode.jmxtrans.JmxTransformer:223) - Loaded file: /usr/share/jmxtrans/kafka-test.json [01 Sep 2015 11:54:33] [main] 5 DEBUG (com.googlecode.jmxtrans.JmxTransformer:297) - Scheduled job: localhost:9999-1441088673052 for server: Server [host=localhost, port=9999, url=null, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:54:33] [ServerScheduler_Worker-1] 9 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:31) - +++++ Started server job: Server [host=localhost, port=9999, url=null, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:54:33] [ServerScheduler_Worker-1] 38 DEBUG (com.googlecode.jmxtrans.util.JmxUtils:95) - ----- Creating 2 query threads [01 Sep 2015 11:54:33] [ServerScheduler_Worker-1] 43 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:50) - +++++ Finished server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:55:33] [ServerScheduler_Worker-2] 60006 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:31) - +++++ Started server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:55:33] [ServerScheduler_Worker-2] 60008 DEBUG (com.googlecode.jmxtrans.util.JmxUtils:95) - ----- Creating 2 query threads [01 Sep 2015 11:55:33] [ServerScheduler_Worker-2] 60014 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:50) - +++++ Finished server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:56:33] [ServerScheduler_Worker-3] 120006 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:31) - +++++ Started server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:56:33] [ServerScheduler_Worker-3] 120008 DEBUG (com.googlecode.jmxtrans.util.JmxUtils:95) - ----- Creating 2 query threads [01 Sep 2015 11:56:33] [ServerScheduler_Worker-3] 120014 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:50) - +++++ Finished server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:57:33] [ServerScheduler_Worker-4] 180006 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:31) - +++++ Started server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] [01 Sep 2015 11:57:33] [ServerScheduler_Worker-4] 180009 DEBUG (com.googlecode.jmxtrans.util.JmxUtils:95) - ----- Creating 2 query threads [01 Sep 2015 11:57:33] [ServerScheduler_Worker-4] 180014 DEBUG (com.googlecode.jmxtrans.jobs.ServerJob:50) - +++++ Finished server job: Server [host=localhost, port=9999, url=service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi, cronExpression=null, numQueryThreads=2] 然而，我试图获得正常的java内存信息，而不是kafka度量，rrd是生成的。如果我有任何配置错误或其他问题，请提出建议。
