tenthe opened a new issue, #4518: URL: https://github.com/apache/streampipes/issues/4518
### Body After the Spring Boot 4 upgrade, `/streampipes-backend/actuator/prometheus` returns `404` even when `SP_SETUP_PROMETHEUS_ENDPOINT=true` is set. The actuator root only exposes `health`, so the Prometheus endpoint is not registered. **Root Cause** Spring Boot 4 expects the new Micrometer Prometheus registry: ```text io.micrometer:micrometer-registry-prometheus ``` StreamPipes currently only has the old simpleclient registry: ```text io.micrometer:micrometer-registry-prometheus-simpleclient ``` **Expected Fix** Add `micrometer-registry-prometheus` so Spring Boot 4 can auto-configure `/actuator/prometheus`, and add e2e coverage to prevent regressions. ### StreamPipes Committer I acknowledge that I am a maintainer/committer of the Apache StreamPipes project. -- This is an automated message from the Apache Git Service.
