JMX ad multiple dimension splitting

[Stephane_LeMoig]

Hello,

i want to collect metrics throught jmx plugin, but split them on more than only one dimension : 

{
"timeseries": {
"key": "metric_put_batch_avg_time_ms_",
"unit": "MilliSecond",
"displayname": "KafkaConnect-put-batch-avg-time-ms",
"dimensions": [
"rx_pid",
"task"
]
},
"source": {
"domain": "kafka.connect",
"keyProperties": {
"type": "sink-task-metrics",
"task": "*"
},
"attribute": "put-batch-avg-time-ms",
"allowAdditionalKeys": true,
"calculateDelta": false,
"calculateRate": false,
"aggregation": "AVG",
"splitting": {
"name": "task",
"type": "keyProperty",
"keyProperty": "task"
}
}
}

In this exemple, it's ok for the dimension "task", but i want to add an other dimension. OK to add the dimension:

"dimensions": [
"rx_pid",
"task",

"connector"
]

But how to add it in the splitting field ? Is there something else to add ?

Thanks.

Hi @Stephane_LeMoig 

Maybe it is not an answer for your question but I have checked a jmx metric with 3 dimensons in an environment with timeseries API and metric API too. See the results, maybe it helps for you.

Timeseries APIv1

{
"timeseriesId": "custom.jmx.PendingRequestCount_V21663771262394:metric_PendingRequestCount_1663771256883",
"displayName": "PendingRequestCount",
"dimensions": [
"PROCESS_GROUP_INSTANCE",
"Process ID",
"Name"
],
"aggregationTypes": [

Thanks for you're suggestion.

It's possible because when i ingest some metrics they can be automatically split on many dimension, but i don't fine any documentation to define this in a custom plugin.

It was a good idea to check th e metrics throught the API, but it doesn't help me much 😞
