Micrometer gauge not appearing on prometheus endpoint

I have instrumented my code inside a method for micrometer gauge like this:

SimpleMeterRegistry registry = new SimpleMeterRegistry();
Gauge
     .builder("greeting_service_gauge", new AtomicInteger(new Random().nextInt(10)), AtomicInteger::get)
     .register(registry);

I have added few other metrics too.

Other metrics appear on prometheus endpoint, but this gauge metrics doesn't.

What am I missing here?

You are registering the gauge to the SimpleMeterRegistry. Instead you should be registering the metric to the Prometheus registry (or the CompositeMeterRegistry)

You can inject the MeterRegistry if this is a Spring project. Or use the global Metrics.globalRegistry to get the composite one.

Gauge
     .builder("greeting_service_gauge", new AtomicInteger(new Random().nextInt(10)), AtomicInteger::get)
     .register(Metrics.globalRegistry);
