About The Project

This simple demo project can be used as an example of setup Prometheus and Grafana to monitor a Spring-Boot application.

The Spring-Boot application is a scheduled task that periodically sends data to console log and micrometer monitoring. And the Prometheus service keeps scraping the data from the exposed actuator prometheus endpoint (http://localhost:8080/actuator/prometheus). Apart from these, the project also contains a demo Grafana dashboard that monitors the JVM information of the Spring-Boot application with JVM (Micrometer).

Built With

• Spring-Boot
• Prometheus
• Grafana
• Micrometer Prometheus
• JVM (Micrometer) dashboard for Grafana

Prerequisites

• install and start Prometheus

  wget https://s3-eu-west-1.amazonaws.com/deb.robustperception.io/41EFC99D.gpg | sudo apt-key add -
  
  sudo apt-get update -y
  
  sudo apt-get install prometheus prometheus-node-exporter prometheus-pushgateway prometheus-alertmanager -y
  
  sudo systemctl start prometheus
  
  sudo systemctl enable prometheus

• install and start Grafana

  echo "deb https://packages.grafana.com/oss/deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list
  
  sudo apt-get update
  
  sudo apt-get install grafana
  
  sudo systemctl daemon-reload
  
  sudo systemctl start grafana-server
  
  sudo systemctl status grafana-server

Usage

• Spring-Boot app - http://localhost:8080/
• Spring Boot Actuator Prometheus - http://localhost:8080/actuator/prometheus
• Prometheus - http://localhost:9090/
• Grafana - http://localhost:3000/ (default username/password: admin/admin)
