- HrrrClient idx-cache test only invalidated the surface idx URL, but
fetch_profile also fetches a pressure idx. Previous runs' state for
the pressure key decided whether the counter landed at 1 (prior run
cached it, pass) or 2 (cold, fail). Invalidate both + assert 2 total
fetches to reflect the actual code path.
- CsvImportTest deadlocked against other async DataCase tests when
inline Oban child jobs upserted iemre_observations/terrain_profiles
with a shared conflict target. Flip to async: false — same fix as
ContactWeatherEnqueueWorkerTest earlier this session.
- PromEx.Plugins.Oban runs a 5s telemetry_poller that queries the DB,
but its poller PID has no sandbox connection in test and crashed
with DBConnection.OwnershipError on every tick, spamming the log.
Gate the plugin on a config flag and skip it in config/test.exs;
prod behaviour unchanged.
Wires PromEx with its built-in Application / BEAM / Phoenix / Ecto /
Oban plugins plus a custom `Microwaveprop.PromEx.InstrumentPlugin`
that registers Prometheus histograms for every
`Microwaveprop.Instrument` span (HRRR/NEXRAD/IEM/GEFS/NARR/UWYO
/Elevation fetches, DB batch upserts, terrain analysis, radar
aggregation, propagation score band). Queue-depth gauges from the
10-second poller land at `microwaveprop_oban_queue_count{queue,state}`.
Router forwards `/metrics` to MicrowavepropWeb.MetricsPlug which
optionally requires a bearer token (`PROMETHEUS_AUTH_TOKEN` env var in
runtime.exs); leave it unset to expose metrics publicly and restrict
at the ingress / Cloudflare Access layer instead.
