I am building a Spring Boot application and planning to use the /actuator/prometheus for data scraping by Prometheus. It seems that the main way is to use Micrometer. However, I see that there is another library, which is Spring Metrics.
What is the go to way to have custom metrics that will be scraped by prometheus?
Early in its development, Micrometer was named Spring Metrics. If you got to the project's GitHub repository (https://github.com/spring-projects/spring-metrics) you will see that it redirects to https://github.com/micrometer-metrics/micrometer as the repository was moving into the micrometer-metrics organization and renamed.
In short, you should use Micrometer.
