ZbTelemetryOptions.Meters/ActivitySources are strict allowlists. The host named only ZB.MOM.WW.OtOpcUa and the LocalDb meter, so the in-process Galaxy driver's galaxy.* spans and its event pump's galaxy.events.* counters (both on "ZB.MOM.WW.OtOpcUa.Driver.Galaxy") were silently dropped from /metrics and OTLP. Found exercising OTLP end to end against a collector (scadaproj#13). - Galaxy driver: public GalaxyDriverTelemetryNames (MeterName / ActivitySourceName); GalaxyTelemetry and EventPump reference it. - Host: ObservabilityExtensions.ObservedMeters / ObservedActivitySources include it. - Host.IntegrationTests: ObservabilityAllowlistTests assert on the listener side (span sampled, instrument enabled) with an unregistered-name negative control; dropping the Galaxy entries fails 3 of 8.
