@bogdandrutu so the constants here

opentelemetry-collector/obsreport/obsreport_exporter.go

Lines 27 to 45 in c7e9b68

	const (
	// Key used to identify exporters in metrics and traces.
	ExporterKey = "exporter"
	// Key used to track spans sent by exporters.
	SentSpansKey = "sent_spans"
	// Key used to track spans that failed to be sent by exporters.
	FailedToSendSpansKey = "send_failed_spans"
	// Key used to track metric points sent by exporters.
	SentMetricPointsKey = "sent_metric_points"
	// Key used to track metric points that failed to be sent by exporters.
	FailedToSendMetricPointsKey = "send_failed_metric_points"
	// Key used to track logs sent by exporters.
	SentLogRecordsKey = "sent_log_records"
	// Key used to track logs that failed to be sent by exporters.
	FailedToSendLogRecordsKey = "send_failed_log_records"
	)

should be changed to private?

Hey I can take on this issue as my first one. So all this entails is to make the constants listed above not public?
