Question

Come vedo un log degli eventi di connessione / disconnessione WiFi?

Ho problemi con il mio router, in cui il WiFi continua a disconnettere dalla maggior parte dei nostri dispositivi domestici, quindi sto testando diverse impostazioni sul router. (Sembra essere influenzato dal protocollo di sicurezza ...)

Mi piacerebbe vedere un log - sul mio MacBook Pro (10.11.5) - degli eventi di connessione / disconnessione WiFi in modo da poter tenere traccia.

Qual è il modo più semplice per farlo? Posso usare qualche tipo di filtro in Console, o c'è un comando CLI?

Ho provato a filtrare "link down on en0" nella console in "All Messsages", ma devo fare clic su "Precedente" molte volte; Mi piacerebbe vedere tutti gli eventi degli ultimi giorni in una volta. E mi piacerebbe anche vedere quale SSID WiFi era in uso al momento della disconnessione, che Console non mi mostra.

Esempio di eventi system.log filtrati:

Per vedere tutti i messaggi di log generati dal kernel durante l'ultimo giorno che contengono il testo AirPort: Link Down , puoi fare:

log show --predicate '(processImagePath contains "kernel") && (eventMessage contains "AirPort: Link Down")' --style syslog --last 1d

Raggiungi la pagina man di log(1) per molte (molto!) ulteriori informazioni.
