Hazelcast Metrics are not showing

[Nirjas Jakilim]

Hi, I am using the following rule to capture hazelcast metrics using JMX.

  - pattern: "^com.hazelcast<type=Metrics,instance=(.+),prefix=(.+),tag0=(.+)><>(.+):"
    name: hazelcast_$4
    attrNameSnakeCase: true
    labels:
      instance: $1
      prefix: $2
      tag0: $3

But the metrics are not showing on /metrics endpoint. but on the log it's showing that the metrics are scraping successfully from mbean.

The log:
18-Apr-2024 04:50:14.448 FINE [prometheus-http-1-1] io.prometheus.jmx.logger.Logger.log com.hazelcast:type=Metrics,instance=hz-auth-inst

HI I was able to fix the problem. So I am going to create a PR to add an example config for hazelcast in prometheus JMX exporter. Thanks
