Dullimeister :
I have activated the spring actuator prometheus endpont /actuator/prometheus. By adding the dependencies for micrometer and actuator and enabled prometheus endpont. How can i get there custom metrics?

You'll need to register your metrics with the Micrometer Registry.
The following example creates the metrics in the constructor. The Micrometer Registry is injected as a constructor parameter:
@Component
public class MyComponent {
private final Counter myCounter;
public MyComponent(MeterRegistry registry) {
myCounter = Counter
.builder("mycustomcounter")
.description("this is my custom counter")
.register(registry);
}
public String countedCall() {
myCounter.increment();
}
}
Once this is available, you'll have a metric mycustomcounter_total in the registry available in the /prometheus URL. The suffix "total" is added to comply with the Prometheus naming conventions.
