Question: Translation of prometheus patterns to jmxfetch queries

[iMajna]

Unfortunately, I cannot find any info about docs about this anywhere and I'm not sure whether it is actually possible when I see implementation but worth of asking.

I'm trying it translate following prometheus rule:

  - pattern: 'kafka.server<type=app-info><>(commit-id|version): (.+)'
    name: kafka_server_$1_info
    value: 1
    labels:
      $1: "$2"
    help: "Kafka server JMX metric info version and commit-id"
    type: GAUGE

That gives me is following output metric:

kafka_server_version_info{version="3.1.0"} 1.0

to Jmxfetch rule.

Reason why I'm doing this is because attribute version is reported as double but in fact it is string and therefore I need to override metric with default value of 1.

$>info -b kafka.server:type=app-info
#mbean = kafka.server:type=app-info
#class name = org.apache.kafka.common.metrics.JmxReporter$KafkaMbean
# attributes
%0 - commit-id (double, r)
%1 - start-time-ms (double, r)
%2 - version (double, r)

So, after I was able to do the same with prometheus rule I'm trying to accomplish the same with jmxfetch as I'm using oob kafka integration to pull jmx metrics.

So, if I tired use something like this:

  {
    "include": {
      "domain": "kafka.server",
      "bean": "kafka.server:type=app-info",
      "attribute": {
        "version": {
          "alias": "kafka.server.cluster.version",
          "metric_type": "gauge",
          "values": {
            "default": 1
          }
        }
      }
    }
  }

but this more or less yields metric kafka.server.cluster.version with value 1 and without tag version=3.1.0 as the one from prometheus rule would as there I could create label out of version attribute through regex. I'm not sure who to do the same here tho.

So, in short, is there a way to somehow send attribute as a label or a tag with its true value along side metric?
