client_java: Prometheus not working after upgrading to Spring Boot Version 2

Hello

I was able to use Prometheus with the Spring Boot Version 2 before without any problem. After updating Spring Boot version to 2.1.1. Release I come across with the following error. I upgraded Prometheus version from 0.2.0 to 0.6.0 but I still come across with the same error . Do you think prometheus is not compatible with Spring Boot Version 2 ? Regards

AFAICT you can use

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

to expose your spring boot 2 application metrics to prometheus.

Path: /actuator/prometheus

Config:

management.endpoints.web.exposure.include=metrics,prometheus
management.endpoint.metrics.enabled=true
management.endpoint.prometheus.enabled=true
management.metrics.export.prometheus.enabled=true

I can’t generallly recommend micrometer, it does some things which don’t make sense in Prometheus instrumentation terms. Generally I’m not a fan of instrumentation facades, they tend to lose you the benefits of the monitoring system you’re using due to having to be be lowest-common-denominator, often encourage anti-patterns, are less performant, and have different resultant metrics depending on the output system.

Micrometer is better than most, but I’d generally recommend using a Prometheus client directly and converting to other monitoring systems as needed by handling registry output. Prometheus clients are designed not to lock you in.

This client library doesn’t support Spring 2.0.

Guess you meant Spring Boot 2.0. Seems they have changed the whole
actuate framework. A comment in the REAME that only Spring Boot < 2 is supported would be nice anyway.
