prop-grid-rs already exposed prop_grid_rs_chain_step_duration_seconds
+ tasks_in_flight on :9100 but the comment still pointed at the old
prom server (10.0.15.25). hrrr-point-rs had no metrics listener at all.
- metrics.rs: new POINT_BATCH_DURATION / POINT_BATCHES_TOTAL /
POINTS_PROCESSED_TOTAL series + record_point_batch helper, plus unit
tests serialized via a static Mutex (the prometheus crate's global
registry races otherwise)
- hrrr_point_worker.rs: spawn metrics::serve on METRICS_ADDR (default
0.0.0.0:9100), wrap process_batch in InFlightGuard, record outcome +
per-point counts on every batch
- deployment-hrrr-point-rs.yaml: prometheus.io/{scrape,port,path,job}
annotations, METRICS_ADDR env, ports.metrics, /health readiness probe
- deployment-grid-rs.yaml: refresh stale 10.0.15.25 comment, add
prometheus.io/job for clean dashboard up{} selectors
Also fix Microwaveprop.PromExTest: `assert plugins != []` triggered
Elixir 1.19 type-checker warning ("non_empty_list != empty_list always
true"); replaced with membership assertions for the InstrumentPlugin +
Plugins.Beam.
