Jmx Json Exporter

Deprecated

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

Getting start

make
./jmx_json_exporter --from [host]:[port]

Then visit http://localhost:9200 ,you can see the metrics.

Params

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

Config

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

Example

There is a jmx json metrics export from http://SomeService:[port]/jmx

        },
        {
            "name" : "Hadoop:service=HBase,name=Master,sub=Balancer",
            "description" : "Metrics about HBase master balancer",

          }
    ]
}

The correspond config will like:

{
  "someService":{
    "java.lang:type=OperatingSystem":[
      {"name":"MaxFileDescriptorCount","type":"Gauge","help":"maxFD"},
      {"name":"OpenFileDescriptorCount","type":"Gauge","help":"help-msg"}
    ]
  },
  "hbase":{
    "Hadoop:service=HBase,name=Master,sub=Balancer":[
      {"name":"BalancerCluster","type":"CustomSummary","help":"BalanceclusterSummary"}
    ]
  }
}

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

or via commandline

./jmx_json_exporter --from node170:9870 --config {\"someService\":{\"java.lang:type=OperatingSystem\":[{\"name\":\"MaxFileDescriptorCount\",\"type\":\"Gauge\",\"help\":\"maxFD\"},{\"name\":\"OpenFileDescriptorCount\",\"type\":\"Gauge\",\"help\":\"help-msg\"}]}}

The Prometheus Metrics will be :

# HELP someService_OperatingSystem_MaxFileDescriptorCount maxFD
# TYPE someService_OperatingSystem_MaxFileDescriptorCount gauge
someService_OperatingSystem_MaxFileDescriptorCount{instance="SomeService"} 4096
# HELP someService_OperatingSystem_OpenFileDescriptorCount help-msg
# TYPE someService_OperatingSystem_OpenFileDescriptorCount gauge
someService_OperatingSystem_OpenFileDescriptorCount{instance="SomeService"} 279
# HELP hbase_Master_BalancerCluster BalanceclusterSummary
# TYPE hbase_Master_BalancerCluster summary
hbase_Master_BalancerCluster{instance="192.168.34.170",quantile="0.25"} 0
hbase_Master_BalancerCluster{instance="192.168.34.170",quantile="0.5"} 0
hbase_Master_BalancerCluster{instance="192.168.34.170",quantile="0.99"} 0
hbase_Master_BalancerCluster_sum{instance="192.168.34.170"} 0
hbase_Master_BalancerCluster_count{instance="192.168.34.170"} 0

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