The ingestion counters of one EventMapping.

Properties​

index​

index: number;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:35

Index of the mapping in the pipeline's mapping list.

channel?​

optional channel?: string;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:37

The mapping's channel pattern, when it declares one.

events_matched​

events_matched: number;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:39

Events whose selectors matched this mapping.

updates_applied​

updates_applied: number;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:41

(entity update, scene) pairs this mapping successfully applied.

drops​

drops: Partial<Record<IngestionDropReason, number>>;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:43

Events this mapping matched but did not apply, by reason.

last_event_at​

last_event_at: Date | null;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:45

When this mapping last matched an event.

continuations_active​

continuations_active: number;

Defined in: livelink.clients/livelink.agent/sources/data/IngestionStats.ts:52

ContinuousUpdates this mapping currently drives. The global gauge answers "is anything moving?"; this one answers "which mapping is moving it?", which is the question with more than one mapping in play — and the one that tells a motion nobody replaced apart from a stream that genuinely stopped.
