What's New
DOCSight now exposes all DOCSIS signal metrics via a Prometheus-compatible /metrics endpoint, enabling integration with Grafana/Prometheus monitoring stacks.
Features
- GET /metrics returns all channel metrics in Prometheus text exposition format (
text/plain; version=0.0.4; charset=utf-8) - Per-channel downstream metrics: power, SNR, correctable/uncorrectable errors, modulation (as numeric QAM order)
- Per-channel upstream metrics: power, modulation
- Summary metrics: health status (0-3), channel counts
- Device info: model, software version, uptime
- Connection info: max downstream/upstream kbps
- Poll timestamp: Unix epoch gauge of last successful modem poll
- No auth required: endpoint is always accessible (like
/health) - No additional modem queries: reads from existing in-memory state
Technical Details
- Pure
format_metrics()function with no external dependencies - 60 new tests (52 unit + 8 integration), 860 total passing
- Closes #59
