Logging Discord Bots

What to check first

• Which events it covers. Message deletion, role changes and voice activity are three different logs and not every bot does all three.
• Whether logs go to separate channels per type, or all into one that becomes unreadable within a week.
• Retention: how far back you can actually look, and whether the bot stores anything or only posts it.
• Whether it can ignore specific channels or bots, so your logs are not mostly other bots talking.

The thing to understand about deleted-message logging is that it can only show what the bot saw. Messages sent before the bot joined are not recoverable, and neither are messages from a channel the bot could not read. That makes this the one category where inviting the bot early has real value even if you never look at the logs — the record starts when the bot arrives, not when you need it.

Volume is the practical problem. A moderately active server generates thousands of log lines a day, and a single channel receiving all of them is a channel nobody reads. Splitting by type — messages here, joins there, moderation somewhere else — is the difference between a log you search and a log you scroll past.

Consider the privacy side as well. A full message log means everything anyone deleted is still readable by your staff, including things deleted for reasons that had nothing to do with rule-breaking. Some servers tell members this is happening. It is a reasonable thing to tell them.
