Questions tagged [spring-micrometer]

Micrometer is the metrics collection facility included in Spring Boot 2’s Actuator. It has also been backported to Spring Boot 1.5, 1.4, and 1.3 with the addition of another dependency.

About

Micrometer is a dimensional-first metrics collection facade whose aim is to allow you to time, count, and gauge your code with a vendor neutral API. Through classpath and configuration, you may select one or several monitoring systems to export your metrics data to. Think of it like SLF4J, but for metrics!
