We can verify this by looking at the targets status page (at It should display two targets, Prometheus itself and our spring-boot app, both with state UP. If we use Maven, we have to add the following lines to our pom.xml file. To use the Micrometer Prometheus plugin we just need to add the appropriate dependency to our project.

You will find lots of resources on the internet describing how to set up a spring-boot app. As an easy option we can create a simple spring-boot application and use the Micrometer Prometheus plugin to write our counter. To better understand the results of our upcoming queries, it’s a good idea to have a little playground where we can create and increase a counter in a simple and controlled way. In this article, I want you to join me on my way to understand how Counters in Prometheus work and how to query them to get the right information. It took me quite some time to understand what I have to do to get the numbers and graphs that I wanted.

It turned out that I had underestimated the complexity of Prometheus Counters.

I assumed that those are the simplest metrics available and it should be easy to extract some meaningful numbers and graphs out of them. I focussed on a couple of already existing counter metrics. I recently had to setup a few monitoring dashboards in Grafana based on a Prometheus data source.
