type Stats

type Stats struct {
	EventCount       counter.Counter
	EventsFiltered   counter.Counter
	NetCapCount      counter.Counter // network capture events
	BPFLogsCount     counter.Counter
	ErrorCount       counter.Counter
	LostEvCount      counter.Counter
	LostWrCount      counter.Counter
	LostNtCapCount   counter.Counter // lost network capture events
	LostBPFLogsCount counter.Counter

	// NOTE: BPFPerfEventSubmit* metrics are periodically collected from the 'events_stats'
	// BPF map, while userspace metrics are continuously updated within the application
	// based on varying logic. Due to differences in data sources and collection timing,
	// the two sets of metrics are not directly synchronized. As a result, the total event
	// counts fetched from 'events_stats' may not align with those reported by userspace metrics.
	// Each metric set is designed to provide distinct insights and should be analyzed
	// independently, without direct comparison.
	BPFPerfEventSubmitAttemptsCount *EventCollector
	BPFPerfEventSubmitFailuresCount *EventCollector
}
