Cannot include Prometheus metrics in spring boot 2 (version 2.0.0.M7) project.
According micrometer docs added spring-boot-starter-actuator dependency and in application.yaml added management.endpoints.web.expose: prometheus but when calling /actuator/prometheus get
{
"timestamp": 1518159066052,
"path": "/actuator/prometheus",
"message": "Response status 404 with reason \"No matching handler\"",
"status": 404,
"error": "Not Found"
}
Tell me please why I wasn't getting prometheus metrics?
Did you add micrometer-registry-prometheus to your dependecies?
Micrometer has a pluggable architecture where you need to define (by plugging dependencies) what monitoring system you'd like to work with. (You can even add multiple, not just one.)
Btw, you should be switching to Spring Boot 2.0.0.RC1. That's the current one as of this writing.
