Hi I'm trying to grab JVM metrics from ```auto -mbean: 'mbean:type=FormatStatus,client=Client,format=Format,ftp=FtpId,FtpProtocol=sftp,FtpServer=server,FtpPort=22,dir=directory,filename=file.txt' attributes: - attr: LastError field: lasterror field_type: string - attr: LastFile field: lastfile field_type: string - attr: LastFileBlankLines field: lastfileblanklines field_type: integer - attr: LastFileError field: lastfileerror field_type: string - attr: LastFileFailedRecords field: lastfilefailedrecords field_type: integer - attr: LastFileLines field: lastfilelines field_type: integer - attr: LastFileLoadTimeMilliseconds field: lastfileloadtimemiliseconds field_type: integer - attr: LastFileLoadedRecords field: lastfileloadedrecords field_type: integer - attr: LastFileLoadedRecordsPerSecond field: lastfileloadedrecordspersecond field_type: integer - attr: Name field: name field_type: string - attr: Status field: status field_type: string ``` but it says no key found is there a way I can manually create the key? Does it mean that I need to add it to the template? ---

Can you run the Metricbeat 6.0.0 snapshot build with the `jolokia.jmx` debug selector enabled and post the log. I added some debug logging to the module that hasn't been released yet, so the [snapshot build](https://beats-nightlies.s3.amazonaws.com/index.html?prefix=metricbeat/) is required to get the extra info in the logs. ```auto logging.level: debug logging.selectors: ['jolokia.jmx`] ``` I'm pretty sure that key not found error indicates that one of the attributes you were expected did not exist in the response. You can have a look at the bean in JConsole to see its attributes. ---

Here is the results in the log. I'm not getting the key error any more but after refreshing the fields list they still aren't showing. I did get to see 2 of the metrics that had errors and commented those out for now. 2017-06-02T12:55:37-04:00 DBG [jolokia.jmx] The response body from jolokia host localhost:7777 is: [{"timestamp":1496422537,"status":200,"request":{"mbean":"java.lang:type=Runtime","attribute":"Uptime","type":"read"},"value":{"Uptime":88637288}},{"timestamp":1496422537,"status":200,"request":{"mbean":"java.lang:type=Memory","type":"read"},"value":{"Verbose":false,"ObjectPendingFinalizationCount":0,"NonHeapMemoryUsage":{"max":136314880,"committed":30081024,"init":24576000,"used":29053128},"HeapMemoryUsage":{"max":492830720,"committed":492830720,"init":33554432,"used":319881352},"ObjectName":{"objectName":"java.lang:type=Memory"}}},{"timestamp":1496422537,"status":200,"request":{"mbean":"java.lang:type=OperatingSystem","attribute":"ProcessCpuLoad","type":"read"},"value":{"ProcessCpuLoad":0.0}},{"timestamp":1496422537,"status":200,"request":{"mbean":"java.lang:type=ClassLoading","attribute":["LoadedClassCount","TotalLoadedClassCount"],"type":"read"},"value":{"LoadedClassCount":3843,"TotalLoadedClassCount":4108}},{"timestamp":1496422537,"status":200,"request":{"mbean":"java.lang:type=Threading","attribute":["DaemonThreadCount","PeakThreadCount","ThreadCount"],"type":"read"},"value":{"PeakThreadCount":38,"DaemonThreadCount":21,"ThreadCount":31}},{"timestamp":1496422537,"status":200,"request":{"mbean":"com.west.wic.campLoad:type=ServerStatus","attribute":["Status","Version"],"type":"read"},"value":{"Status":"Running","Version":"4.1.9 (20170331-0910 - radupa)"}},{"timestamp":1496422537,"status":200,"request":{"mbean":"com.west.wic.campLoad:FtpPort=22,FtpProtocol=sftp,FtpServer=127.0.0.1,client=client,dir=_data\_client\_Seasonal\_Allergy\_inputs\_Processed,filename=ALLERGY\_REFILL_\_.MERGED.DUPLICATES,format=seasonalallergy,ftp=FtpId12,type=FormatStatus","attribute":["LastError","LastFile","LastFileBlankLines","LastFileError","LastFileFailedRecords","LastFileLines","LastFileLoadedRecords","Name","Status"],"type":"read"},"value":{"Name":"client - seasonalallergy","Status":"ready","LastFile":null,"LastFileLoadedRecords":0,"LastFileFailedRecords":0,"LastFileLines":0,"LastError":null,"LastFileBlankLines":0,"LastFileError":null}}] ---

I formatted the response JSON to make it easier to read. ```auto [ { "timestamp": 1496422537, "status": 200, "request": { "mbean": "java.lang:type=Runtime", "attribute": "Uptime", "type": "read" }, "value": { "Uptime": 88637288 } }, { "timestamp": 1496422537, "status": 200, "request": { "mbean": "java.lang:type=Memory", "type": "read" }, "value": { "Verbose": false, "ObjectPendingFinalizationCount": 0, "NonHeapMemoryUsage": { "max": 136314880, "committed": 30081024, "init": 24576000, "used": 29053128 }, "HeapMemoryUsage": { "max": 492830720, "committed": 492830720, "init": 33554432, "used": 319881352 }, "ObjectName": { "objectName": "java.lang:type=Memory" } } }, { "timestamp": 1496422537, "status": 200, "request": { "mbean": "java.lang:type=OperatingSystem", "attribute": "ProcessCpuLoad", "type": "read" }, "value": { "ProcessCpuLoad": 0 } }, { "timestamp": 1496422537, "status": 200, "request": { "mbean": "java.lang:type=ClassLoading", "attribute": [ "LoadedClassCount", "TotalLoadedClassCount" ], "type": "read" }, "value": { "LoadedClassCount": 3843, "TotalLoadedClassCount": 4108 } }, { "timestamp": 1496422537, "status": 200, "request": { "mbean": "java.lang:type=Threading", "attribute": [ "DaemonThreadCount", "PeakThreadCount", "ThreadCount" ], "type": "read" }, "value": { "PeakThreadCount": 38, "DaemonThreadCount": 21, "ThreadCount": 31 } }, { "timestamp": 1496422537, "status": 200, "request": { "mbean": "com.west.wic.campLoad:type=ServerStatus", "attribute": [ "Status", "Version" ], "type": "read" }, "value": { "Status": "Running", "Version": "4.1.9 (20170331-0910 - radupa)" } }, { "timestamp": 1496422537, "status": 200, "request": { "mbean": "com.west.wic.campLoad:FtpPort=22,FtpProtocol=sftp,FtpServer=127.0.0.1,client=client,dir=dataclient_Seasonal_Allergy_inputs_Processed,filename=ALLERGY_REFILL__.MER, "attribute": [ "LastError", "LastFile", "LastFileBlankLines", "LastFileError", "LastFileFailedRecords", "LastFileLines", "LastFileLoadedRecords", "Name", "Status" ], "type": "read" }, "value": { "Name": "client - seasonalallergy", "Status": "ready", "LastFile": null, "LastFileLoadedRecords": 0, "LastFileFailedRecords": 0, "LastFileLines": 0, "LastError": null, "LastFileBlankLines": 0, "LastFileError": null } } ``` ---

I did get 500 or so new fields with the new version of metricbeat. 1 of which conflicts haproxy.stat.check.health.last which was set to number but is now set to string. But I don't think that would be preventing the fields. I was wrong the message is showing this still { "message": "6 errors: metric key '' not found in response; metric key '' not found in response; metric key '' not found in response; metric key '' not found in response; metric key '' not found in response; metric key '' not found in response" } ---
