Metrics publisher is a small, standalone service provisioned as a Proxmox LXC on srv-01 which publishes health telemetry to this dashboard on a 1-minute interval.
What it reports
- CPU / RAM / load; live host utilisation
- Uptime; since the last host boot
- Guests; VM + container counts (and how many are running)
- Storage; pool usage
- Internet; edge reachability + round-trip latency
How it works
Metrics publisher runs a cron job, capturing local health telemetry from srv-01 on an interval timer and posting it to an ingestion endpoint on this site. This service is security-forward, only exposing outbound traffic and masking sensitive data (i.e. IP addresses, host names, etc.). Telemetry is upserted using Upstash Redis.
