This is a poc using Spring Boot 2.2 and Prometheus Push Gateway with Micrometer.
The Prometheus Pushgateway exists to allow ephemeral and batch jobs to expose their metrics to Prometheus. Since these kinds of jobs may not exist long enough to be scraped, they can instead push their metrics to a Pushgateway. The Pushgateway then exposes these metrics to Prometheus.
First, run the command bellow:
docker run -d --net=host --name=prometheus-pushgateway prom/pushgateway:latest
Second, open the browser and access the address http://localhost:9091
Start the application
mvn spring-boot:run
First, call the endpoint http:\\localhost:8080\hello
Second, open the Prometheus Push Gateway http:\\localhost:9091 and see the measurements, mainly the hello-counter
Third, be happy
