Spring Boot Actuator does not show http.server.requests in metrics endpoint after spring-boot upgrade to 3.*

[strivedi7]

I do have a spring boot project developed using Java 17 in which I am adding the spring boot actuator and Prometheus to use the metrics endpoint to analyze the API http.server.requests.

I do check metrics using http://localhost:8080/metrics I cannot find http.server.requests in response. It was working fine with the older spring-boot (2) version.

Java: openjdk 17.0.10

Dependencies

org.springframework.boot:spring-boot:3.1.10 (c) org.springframework.boot:spring-boot-actuator:3.1.10 (c) org.springframework.boot:spring-boot-actuator-autoconfigure:3.1.10 (c) org.springframework.boot:spring-boot-starter:3.1.10 (c) org.springframework.boot:spring-boot-starter-actuator:3.1.10 (c)

io.micrometer:micrometer-core:1.11.10 (c) io.micrometer:micrometer-observation:1.11.10 (c) io.micrometer:micrometer-registry-prometheus:1.11.10

Config

{
    "management.metrics.distribution.percentiles-histogram.http.server.requests": {
        "value": "true"
    },
    "management.endpoint.health.show-details": {
        "value": "always"
    },
    "management.endpoints.web.exposure.include": {
        "value": "*"
    }
}

Please let me know if you need any additional info or logs.

Can you share a minimal sample application (a single hello web endpoint is enough) that reproduces the problem? Ideally something we can git clone or unzip. Thanks!
