droppedEventCount

Total event emissions rejected since this client was created.

The default BufferOverflow.DROP_OLDEST overflow mode means tryEmit never returns false; losses as silently discarded oldest events are not observable via this counter. This counter observes rejected emissions for BufferOverflow.SUSPEND overflow clients. For no-subscriber BufferOverflow.SUSPEND clients, emissions beyond the base event buffer capacity are treated as rejected because there is no collector available to drain them.
