Replacing Watchtower with WUD on Synology: Docker Updates, Portainer and Telegram
How I migrated from Watchtower to What's Up Docker on Synology, with selective 02:00 auto-updates, Portainer, Telegram alerts and a real Plex update test.
Category Monitoring
Monitoring projects using Grafana, Prometheus, Home Assistant and custom dashboards to observe Realm Labs systems.
Automating Docker Updates on Synology with Watchtower, Portainer and Telegram
My working Synology Docker watchdog: Watchtower checks selected Portainer containers at 2 AM, recreates updated images, and alerts via Telegram only on changes or failures.
Moving Grafana and Prometheus from Synology Docker to Proxmox LXC — Without Losing History
A real homelab migration from Synology Docker to Proxmox LXCs: Grafana dashboards, Prometheus TSDB history, SNMP Exporter, Synology-hosted YAML sync, NFS gotchas, rollback and actual RAM savings.
Grafana Suddenly Slow? Tracing a Docker MAC Address Collision
Grafana dashboards became painfully slow even though CPU and RAM looked fine. The real cause was a duplicate Docker MAC address on a Synology-hosted bridge network — and the fix exposed a useful lesson about stale neighbour entries too.
Monitoring Proxmox LXC Containers Accurately with Prometheus and PVE Exporter
How I made the KITT Control Centre match Proxmox LXC CPU, RAM and disk figures by combining prometheus-pve-exporter with node_exporter, Prometheus and PromQL.
Monitoring My Entire Home Lab with Home Assistant, Prometheus and Grafana
Monitoring Realm Labs didn’t start as one big project. Like most things in the home lab, it grew. Initially, I just wanted to know whether a Raspberry Pi was getting hot. Then I wanted to know what Proxmox was doing.…
Raspberry Pi MQTT Monitoring with Home Assistant
Monitor Raspberry Pi CPU, memory, disk, temperature and uptime in Home Assistant using Python and MQTT, with current Paho 2.x guidance and stale-data protection.
Running Uptime Kuma in a Proxmox LXC for Simple Home Lab Monitoring
As Realm Labs grew, I already had Prometheus and Grafana giving me detailed metrics about the infrastructure. CPU load. Memory. Storage. Network interfaces. Service performance. That was useful, but it answered a very specific question: What I also wanted was…
