Ed Welch's guide explores the integration of monitoring tools OSSEC, Loki, Prometheus, and Grafana on a Raspberry Pi to enhance home network security and visualize alerts. The setup begins with OSSEC for real-time email alerts and evolves to using Loki, Prometheus, and Grafana for a comprehensive view of these alerts, eliminating the need for manual log searches. Welch details the installation and configuration processes for each component, emphasizing that the project is experimental and not production-ready. The tutorial includes creating systemd services to ensure components run on boot, with a focus on simplifying and visualizing network activity through Grafana dashboards. The guide concludes with steps to import pre-built dashboards into Grafana, ultimately allowing users to run a scalable monitoring system on a cost-effective Raspberry Pi.
