Logging
Turn on the audit log to keep a running record of what happens on your server: messages deleted or edited, members joining and leaving, timeouts, kicks, bans, and AutoMod hits.
Pick a channel for the log under Bot settings and choose which events you care about. It is the quickest way to catch up on a busy day.
How long logs are kept
Log retention follows your plan - Starter 7 days, Pro 20, Team 40. Lifetime and Custom tiers can differ. Older entries roll off automatically once they pass your window, so the log stays fast. See Plans & billing.
