Podcast, episode 4: Is It Up? — Uptime, Alerts, and the Metrics Stack

This episode covers the essentials of monitoring your homelab, including how to use Uptime Kuma to check if services are up, setting up phone alerts with ntfy, and building a metrics stack with Prometheus and node_exporter. It also discusses how to handle alerts when they fire, referencing the book 'Watch Your Homelab', and covers recent news on ransomware, new single-board computers, and a blog post on backdooring Bash.
