This repository contains an monitoring-stack.yml file, which is a Docker Compose file for creating containers for prometheus, grafana, grafana-loki and node-exporter.
# Starting the containers
$ docker compose -f ./monitoring-stack.yml up -d
# List all running containers
$ docker ps
# Stopping the containers
$ docker compose -f ./monitoring-stack.yml downGrafana provides an Web UI for monitoring the metrics; it can be accessed at http://<your_ip_here>:3000 with the default username and password as admin

NOTE node-exporter should be hosted along with the application server, not with the monitoring stack. The project's monitoring stack assumes that both the monitoring stack and the application server run on the same physical device.
The project also includes grafana dashboards, which are given below and can be used to create a simple dashboard for visualizing metrics.
