Grafana

Monitoring

Open-source dashboards and alerting for any metrics data source.

Grafana is the industry-standard open-source platform for building dashboards and alerts from virtually any data source — Prometheus, Loki, InfluxDB, PostgreSQL and 100+ more via plugins. Paired with Prometheus and Loki it forms the classic self-hosted observability stack for monitoring homelab infrastructure and applications.

Resource footprint

512 MB RAM · 0.5 CPU

512 MB RAM / 0.5 core comfortably renders dozens of dashboards for a homelab. Grafana itself only visualizes data — the real resource cost usually comes from the data sources it queries (Prometheus, Loki, InfluxDB) running alongside it.
