alphagov.prometheus_demo's Introduction

prometheus_demo - Client Java

As part of research into Prometheus, a project based on Spring Boot and JPA has been created. The project includes:

Basic Spring Boot code
JPA libraries and basic code to call the DB

This is part of the exploration of the Client Java

There are some exporters and integrators to be used with different DBs. They can be found here

Steps we followed

Here are the steps we followed that should be repeatable:

# Compile the application
mvn install

# Run the application
java -jar target/prometheus_demo-0.0.1-SNAPSHOT.jar
