您需要使用Micrometer Registry注册您的指标.

以下示例在构造函数中创建度量标准.Micrometer注册表作为构造函数参数注入:

@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();
    }
}

一旦可用,您将在/ prometheus URL 中的注册表中获得指标mycustomcounter_total.添加后缀"total"以符合Prometheus命名约定.
