弹簧启动Prometheus，千分尺无法发布数据

Question

I am using micrometer to publish some event

import io.micrometer.core.instrument.Metrics; 

/**
 *
 * @param eventName : event name to publish
 */
public static void recordEvent(String eventName){
    Metrics.counter(eventName).increment();
}

and calling it from my application class like this

 metricsCollector.recordEvent("metric name");

and mapping prometheus end point like this in properties file

endpoints.prometheus.path=metrics

but when i go to the http://localhost:8082/metrics i am not able to see the event

I assumed it to be some problem with the registry and tried to add registry like this

 Metrics.addRegistry(new CompositeMeterRegistry());

but it also didn't worked out.

Spring boot version : 1.5.9
Java version 1.8

Spring Boot 1.x doesn't have built-in support for micrometer. That's in Spring boot 2.x. For custom metrics in Spring Boot 1.x see here: https://docs.spring.io/spring-boot/docs/1.5.9.RELEASE/reference/htmlsingle/#production-ready-enabling
