Public by design
Safe resource measurements reach the public portal. Logs and detailed identities stay in the authenticated Grafana account.
A little Pi. Clear field notes.
The companion guide to Raspberry observability. Follow the data from silicon to screen, understand what it can tell you, and know what to do when the signal changes.
Small footprint
Native collection, short queues, and bounded storage protect a small microSD card. No local historical database is required.
Every signal explained
The reference comes from a pinned, machine-readable catalog. Unsupported hardware measurements remain explicitly unavailable.
Built for recovery
Runbooks cover power, temperature, disk pressure, lost telemetry, delivery failures, and safe rollback.
The portal and native collectors are deployed with real Pi measurements and private Grafana alerting. Release notes record verified recovery tests, current limitations and the wiki certificate status.
