Prometheus client compatibility with Springboot 2.*?

[Clay Vass]

Hi all I am sure this gets asked alot, but was unable to find a good answer online to my question.

Is the prometheus java client (https://github.com/prometheus/client_java) able to record & export metrics if I am measuring against a JVM application that depends on springboot 2.*?

Hello Clay,

We do not have any auto-instrumentation for Spring Boot. The reason is that Spring Boot ships with Micrometer built-in. Micrometer provides a lot of useful out-of-the-box metrics, and it is easy to add custom metrics.

dependencies:

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

application.properties

management.endpoints.web.exposure.include=prometheus

Scrape URL: http://localhost:8080/actuator/prometheus

I would recommend using Micrometer, as it ships with Spring Boot. If there's any reason why that doesn't work for you, let me know.

Fabian - 

I guess I am asking more of, can I use prometheus client with a java service built with springboot 2.*? 

I understand I cannot perform some auto instrumentation, but I would like to create histograms/gauges/counters, and expose those, both via the prometheus java client library. Is this possible if my service relies on springboot 2.*?
