📈 Metrics (Grafana stack)

Here you’ll find a few observability notions concerning metrics, along with my personal metrics stack for the VPS hosting farnetiandrea.it.

Four components, two machines (VPS + a dedicated scraper VM):

• Node Exporter: host-native exporter on the VPS, exposes system metrics on :9100/metrics.
• VMAgent: runs on a dedicated VM, pulls metrics from the VPS targets and forwards them via remote_write to VictoriaMetrics.
• VictoriaMetrics: Docker container on the VPS, TSDB and PromQL query engine.
• Grafana: Docker container on the VPS for dashboards and visualization, exposed publicly at farnetiandrea.it/metrics as a read-only public preview.
