Analytics
Your project's Analytics tab shows real command activity over the last two weeks: total runs, success and error counts, response time, a daily trend chart, and which commands get used the most. Click a recent run to see its exact step-by-step trace, which block it stopped at and why, useful for tracking down why a specific command failed for someone.
Audit Log module
A dedicated module that posts a running feed of server activity, message edits and deletions, member joins/leaves/updates, bans, AutoMod actions, channel and role changes, and more, to one channel you choose. Turn it on from your Modules tab and optionally pick which categories to include, leaving none checked logs everything it supports. High-volume events (every single message, every reaction, typing) are deliberately never included, to keep the channel readable.
Tip: Analytics answers "how is my bot doing overall", the Audit Log module answers "what happened in my server", they're complementary, not overlapping.
