Monitoring side of quantus/miner#9. The miner now exports build identity,
per-device and per-job series (quantus/miner#14); this makes them readable.
- asset/prometheus/quantus-rules.yml: recording rules joining the miner's
series with the GPU series on a derived `host` and device index —
hashrate by device and commit, hashrate per watt, batch time off the GPU,
stale work, seal latency p95, idle waiting for the node.
- script/infra-setup.sh (metrics role): prometheus.yml gains `rule_files:`
for /etc/prometheus/rules.d, guarded like scrape_config_files; the dir;
a sudoers grant for the rules file.
- deploy.yaml deploy-metrics: pushes the rules (reload is already gated on
content change); validate asserts the quantus-miner rule group loaded.
- asset/grafana/quantus.json: "Performance by build" row, eight panels, and
a deploy annotation from changes in miner_build_info. No credentials
involved; Prometheus is the annotation source.
- asset/gpu/nvidia-textfile.sh (gpu role, operator-shipped): five
nvidia_gpu_event_reason_active{reason=...} gauges from nvidia-smi's clock
event reasons, so a regression that coincides with thermal or power-brake
capping can be told from a code regression.
