Homelab Capacity Planning: What If a Node Dies Tonight?
I built a read-only simulator that answers whether a dead node's containers fit on the survivors — using the RAM they actually use, not the RAM you configured.
Track AI Token Spend in Grafana: Claude, Codex, and Ollama
Wire every Claude Code, Codex, and Ollama call into Prometheus and one Grafana dashboard — tokens, latency, cache hits, and real dollars vs quota burn.
Real Screenshots, Zero Leaks: My Disposable Demo Lab
How this site captures real, publish-safe homelab screenshots — a throwaway demo lab plus headless Chrome, with no mockups and no leaked IPs.
The Docker localhost Trap: 24 Hours of Red, Zero Real Downtime
My Uptime Kuma monitors logged 24 hours of red while every service was up. Inside a Docker container, localhost isn't your machine — here's why, and the fix.
One UPS, Whole Homelab: Safe Auto-Shutdown with NUT
Use Network UPS Tools (NUT) so a single UPS can cleanly shut down every machine in your homelab when the power fails — one server, many network clients, step by step.
The Self-Healing Arr Stack: Why My Watchlist Silently Stopped Downloading
A real homelab incident — rotated API keys silently killed my Arr automation for days with zero errors. Here's the debugging story and the four patterns that make media automation immune to it: runtime keys, one consolidated script, an auto-detecting VPN-leak check, and a dead-man's-switch alert.
Prove Your Homelab Docs Are Actually Up to Date
A knowledge base with many derived views is only trustworthy if every view proves it's current. The operations chapter: consumer parity, commit-matching health checks, a backup mirror, and correct failure behavior.
Uptime Kuma: Dead-Simple Homelab Monitoring Before You Touch Grafana
Uptime Kuma is the easiest way to monitor your homelab — know the moment a service goes down, with notifications to your phone. A beginner Docker guide to up/down monitoring and status pages.
Node Exporter + pve-exporter: Complete Proxmox Metrics in Grafana
Install node_exporter on every Proxmox node and pve-exporter for cluster-level metrics, wire both into Prometheus, and import production-ready Grafana dashboards — with alert rules for the metrics that actually matter.
Proxmox Monitoring with Prometheus and Grafana: Full Stack Setup
Deploy a complete observability stack for a Proxmox cluster: node_exporter on all hosts, pve-exporter for cluster metrics, Prometheus scraping everything, and Grafana dashboards with email alerting.
