in the fleet mode.

I don't see anything here that would make this only function while under fleet? Maybe I'm missing something.

The change is introduced in the adjustFleetEvent function, that is only called in fleet mode:

beats/metricbeat/module/apache/status/status.go

Lines 98 to 100 in ad10da0

	if m.isFleetMode {
	event = adjustFleetEvent(event)
	}
