A practical setup guide for pushing Proxmox metrics to InfluxDB 2.0 and visualizing them with Grafana in a homelab environment. Covers installing InfluxDB 2.0 as a systemd service (without sudo), installing Grafana, connecting the two, using a pre-built Proxmox dashboard, and optionally configuring TLS certificates for both services. The goal is to track resource usage across VMs, hosts, and containers to help with sizing decisions.

How do I send Proxmox metrics to InfluxDB and view them in Grafana?
Proxmox can push metrics directly to InfluxDB 2.0. Install InfluxDB 2.0 as a systemd service (accessible on port 8086), initialize it with an admin password, then install Grafana (accessible on port 3000). Configure Proxmox to send metrics to InfluxDB, connect Grafana to InfluxDB as a data source, and import a pre-built dashboard such as Grafana dashboard ID 15356 for Proxmox. TLS can be added to both services separately. Homelab engineers tracking VM and container resource usage share setups and dashboards on daily.dev.
