New Post: Grafana + Prometheus on Docker — Complete Homelab Monitoring Stack
Hey there,
We just published a new guide on the blog: Grafana + Prometheus on Docker: The Complete Homelab Monitoring Stack Guide.
If you've ever wondered why your homelab felt like a black box — services going down quietly, disk filling up overnight, containers chewing through CPU for no obvious reason — this one's for you.
In the post, Alex walks through deploying a full Grafana + Prometheus monitoring stack with Docker Compose, covering:
- How Prometheus, Grafana, Node Exporter, and cAdvisor work together
- Complete Docker Compose setup you can copy and run today
- Essential PromQL queries for CPU, memory, disk, and container metrics
- Importing community dashboards (Node Exporter Full, cAdvisor)
- Setting up alerting rules for high CPU, low disk, and scrape target failures
- Expanding to Blackbox Exporter probes and Home Assistant sensor data
As always, feel free to reply with questions or requests for the next topic.
