logs becoming enormous ~ 17 G! Is it OK to delete manually?

[EdNett]

Hello,

Certain logs are becoming huge on a just updated (barracuda + octopus) lts:

var/log/scan_nginx_flood_debug.log = 11 G
var/log/scan_nginx_admin_debug.log = 5 G
var/log/scan_nginx_other_debug.log = 1 G

Shouldn't these be rotated, or should we just delete them occasionally?
Can we safely delete them or do we have to truncate them, leaving the log file in place?
Does this indicate a problem with this vps undergoing too many hacking attempts?

boa info more is here: https://gist.github.com/EdNett/d009560edb7b1fc15a9cdd8992e56126

Thank you.

Ed

It should be safe to just delete those log files.

You might want to check your logging level too. You might have set this to verbose, which you should probably only use for debugging.
