I'm not maintain it,beacuse it is so so so bad, you can use it just for fun 😬
Export Dropwizard Metrics
（also called Yammer Metrics）from /jmx endpoint to Prometheus Metrics.
It suitable for hadoop,hbase,spark... who using Deopwizard Metrics and exporter to http interface.
There are also some OOTB exporters, see: Hadoop Exporter , Hbase Exporter, Zookeeper Exporter
make
./jmx_json_exporter --from [host]:[port]Then visit http://localhost:9200 ,you can see the metrics.
| option | default | description |
|---|---|---|
| --from | localhost:8080 | jmx json endpoint |
| --port | 9200 | output port |
| --path | /metrics | output path |
| --config | "{}" | json type config string |
| --config-file | ./config.json | config file json |
a json format config in file or via commandline is needed:
{
"namSpace":{
"foo":[
{"name":"foo","type":"typeGauge","help":"help-msg"},
{"name":"bar","type":"typeCustomSummary","help":"help-msg"}
],
"bar":[
{"name":"foo","type":"typeCustomSummary","help":"help-msg"},
{"name":"baz","type":"typeCustomSummary","help":"help-msg"}
]
}
}note: The type filed only support Gauge,CustomConter,CustomSummary .
config json support multi nameSpace
There is a jmx json metrics export from http://SomeService:[port]/jmx

}The correspond config will like:

},

}
}For Summary metrics only use thr prefix,"BalancerCluster_mean" using "BalancerCluster".

The "OperatingSystem" is auto detected from string"java.lang:type=OperatingSystem", 'name' or 'type' will be used.
