JMXtrans 不为神经节创建卡夫卡指标的 rrd

Question

我正在尝试使用jmxtrans和ganglia监控kafka代理。然而，对于下面的json，没有创建rrd。

{
"servers": [
    {
        "port": "9999",
        "host": "localhost",
        "queries": [
            {
                "outputWriters": [
                    {
                        "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",
                        "settings": {
                            "groupName": "kafka topic stats",
                            "port": 8649,
                            "host": "localhost",
            "typeNames":[
                "name"
            ]
                        }
                    }
                ],
                "obj": ""kafka.server":type="BrokerTopicMetrics",name="*"",
                "resultAlias": "Kafka",
                "attr": [
                    "Count",
                    "OneMinuteRate"
                ]
            },
            {
                "outputWriters": [
                    {
                        "@class": "com.googlecode.jmxtrans.model.output.GangliaWriter",
                        "settings": {
                            "groupName": "kafka server request",
                            "port": 8649,
                            "host": "localhost"
                        }
                    }
                ],
                "obj": ""kafka.network":type="RequestMetrics",name="Produce-RequestsPerSec"",
                "resultAlias": "produce",
                "attr": [
                    "Count",
                    "OneMinuteRate"
                ]
            }
        ],
        "numQueryThreads": 2
    }
]
} 

jmxtrans.log中打印的日志是

然而，我试图获得正常的java内存信息而不是kafka度量，生成了rrd。请建议如果我做任何配置错误或其他。

从日志文件中可以看到，没有向gmond发送指标。你在json文件中有错误。对于正确的工作替换为:

"obj": "kafka.server:type=BrokerTopicMetrics,name=*",和

"obj": "kafka.network:type=RequestMetrics,name=Produce-RequestsPerSec",重启jmxtrans守护进程，你应该看到在jmxtrans日志文件相同:

[12 Sep 2015 01:25:11] [pool-22-thread-1] 630550 DEBUG (com.googlecode.jmxtrans.util.JmxUtils:195) - Executing queryName: kafka.server:name=BytesInPerSec,type=BrokerTopicMetrics from query: Query [obj=kafka.server:type=BrokerTopicMetrics,name=*, resultAlias=Kafka, attr=[Count, OneMinuteRate]]
