Spring hikari datasource metrics not visible on prometheus endpoint about spring-boot

[abhisheksurve45]

I see property metrics-tracker-factory in hikari

example

 datasource:
    url: jdbc:mysql://x.x.x.x:xxxx/xxx
    username: xxxx
    password: xxxx
    driver-class-name: com.mysql.cj.jdbc.Driver
    name: xxxx
    hikari:
      pool-name: xxxx
      metrics-tracker-factory: ?

But I'm not sure how to set it.

Ive initialised the Micrometer MeterRegistry via

@Bean
    public MeterRegistry getMeterRegistry() {
        return new CompositeMeterRegistry();
    }

org.springframework.boot.actuate.autoconfigure.metrics.jdbc.DataSourcePoolMetricsAutoConfiguration.HikariDataSourceMetricsConfiguration should set this up automatically. It sounds like that may not be happening for you but I cannot tell why without some more information about your application.

If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

Sure @wilkinsona

I could see code going through com.zaxxer.hikari.metrics.micrometer.MicrometerMetricsTracker#MicrometerMetricsTracker constructor and metrics being registered, however they don't appear on actuator endpoint.

Will create a small POC.
