Send log to Kiwi vs Save in a log file

Hi there,

             I'm trying to figure out which way is better? Correct me if I'm wrong.

             Currently, I want to change log level from critical to notification. I tried to avoid fill up log storage in the swtich (e.g. 3850)

1. Kiwi: I need to change console log level in order to send notification logs to kiwi, which all the notification logs would store locally in the switch then.

2. Log file (logging logfile logfile-name severity-level [ size bytes ]):  I can just change saving log file level to notification, and still store critical logs locally in the switch.

           If I'm right about the concept, wouldn't it be better to store syslogs in a log file instead of sending to kiwi?

               Thank you!!

Best,

Lionel
