Built to watch over multiple nodes with dozens of drives, streaming SMART health, ZFS pool status, I/O rates, and temperatures to a single dashboard over WebSocket. Alerts go to Gotify. + +## Why + +Every time I looked for a way to keep tabs on disk health across all the nodes in my home rack, the answer was always the same stack: Grafana, Telegraf, Prometheus, maybe throw InfluxDB in there too. That is an absurd amount of infrastructure just to answer "are my drives dying?" I didn't need time-series databases and query languages and dashboarding frameworks. I needed something that tells me if a disk is getting hot, if a ZFS pool is degraded, or if SMART errors are creeping up, across every machine, in one place. + +Nothing out there was built for this. Everything either does way too much or only monitors the local machine. So I wrote ZPulse. It is purpose-built for home racks: lightweight agents that stream disk and ZFS telemetry over a single WebSocket connection to one central dashboard. No metric pipelines, no config files longer than the code itself, no containers, no databases. Just a Python agent on each node and a dashboard on whatever box you have lying around. + +## Preview +![](./.screens/preview.png) +![](./.screens/preview2.png) + +## Architecture + +``` +[Server 1] agent.py ──WebSocket──┐ +[Server 2] agent.py ──WebSocket──┼──> [Central Box] dashboard.py <──WS──> [Browser] +[Server N] agent.py ──WebSocket──┘ +``` + +- `agent.py` runs on each server as root, collects disk/ZFS/SMART/I/O data, & streams it to the dashboard +- `dashboard.py` runs on a central machine *(Raspberry Pi, NUC, whatever)*, aggregates data from all agents, & serves the web UI +- All data flows over persistent WebSocket connections, no polling + +## Dashboard Setup + +Installs to `/opt/zpulse-dashboard`.
