Metrics

Trying to switch to coffee-boots, previously I could get metrics on the caches via prometheus and micrometer, when I switch to configuring the caches with coffee-boots they drop off the metrics endpoints. Any thoughts on how to get them back? I am using the same caffeinespec for all the caches, just changing the configuration from spring.cache... to coffeeboots.cache...

Thanks for pointing this out, I’ll check

👍 I don't have a sample project, but am using spring-boot with:

        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
        </dependency>

and looking at /actuator/prometheus endpoint

Would you please also tell which versions of spring-boots, micrometer and coffee-boots do you use?

Seems that it's the way Spring Boot works now:

In short: metrics do not work out of the box for dynamically created caches.

But I'll check a bit more.
