Overview

Contatori diagnostici thread-safe del client: quanti eventi sono stati accodati, scartati (coda piena / before_send / sampling), spediti con successo, falliti (rete o status non-2xx) e, tra i falliti, quanti per timeout di rete. Rendono visibili i fallimenti silenziosi del trasporto fire-and-forget. timeout è un sotto-conteggio di failed (un timeout resta un fallimento d'invio): li teniamo distinti per isolare i problemi di connettività dai non-2xx.

CloseYourIt.stats.to_h # => { enqueued: 12, dropped: 0, sent: 11, failed: 1, timeout: 1 }
