JMX Exporter config for MBean attributes

[Martin Schneppenheim]

I use the JMX exporter to export JMX metrics in the Prometheus format and I managed to make it work for most the JMX metrics. But some JMX metrics are different and therefore I probably need to adapt the JMX exporter config accordingly.

I couldn't manage to export the JMX metrics as shown in JConsole (see screenshot). Among many other configurations I tried this:

```

- pattern: kafka.server<type=socket-server-metrics, listener=(.+), networkProcessor=(.+), name=(connection-count|connection-creation-rate)><>Value
name: "kafka_server_socket_server_metrics"
labels:
listener: $1
network_processor: $2
type: $3

```

This ended up with no metrics for this metric name. How is the exporter config supposed to look like for these MBeans?

Best,

Martin.

Martin,

I use the follow pattern to pull out socket server metrics:

```

# kafka.server:type=socket-server-metrics,listener={listener_name},networkProcessor={#}

- pattern: kafka.(\w+)<type=(.+), (.+)=(.+), (.+)=(.+)><>([a-z-]+)

  name: kafka_$1_$2_$7

  type: GAUGE

  labels:

    "$3": "$4"

    "$5": "$6"

```
