Metric reference

What each card on Growth, Engagement, Audience, Leaderboards and Lens counts.

Every plan

Every card follows the view's date range and filters, and counts in the server's time zone. Colossus counts what messages carry, never their text.

Growth

Under Health › Growth. Cards narrow by role, not by channel.

Members: The server's member count at the end of each period, as Discord reports it. Always the whole server.
Net growth: Joins minus leaves. Members who come back are shown apart from new ones.
Boosts: Server boosts active at the end of each period.
Join sources: Joins by way in: an invite, the vanity URL, Server Discovery, a bot or an integration.
Joins by hour: Joins by weekday and hour.
Newcomer replies: Of joiners who sent a first message, the share answered within a day.
Activation: The share of joiners who posted or joined voice within 7 or 30 days.
Role uptake: The share of joiners who picked up any role within 7 or 30 days.
Retention: The share of each period's joiners still in the server after 7 or 30 days. These four stop 7 or 30 days before today, while the newest joiners' window runs.
Leavers by segment: Leavers by the segment they were in when they left.
Tenure at leaving: How long leavers had been members.

Under Health › Engagement. Cards narrow by role and by channel.

Messages: Messages per period, split by text, attachments, links, GIFs and stickers.
Reply share: The share of messages that reply to another.
Reply time: How long replies took, from under a minute to over two hours.
Reactions per message: Reactions given per message.
Voice time: Minutes in voice, split into speaking, muted and away.
Streaming and camera: Minutes sharing a screen or on camera.
Moderation: Deleted messages, timeouts and bans, without who or why.
Activity by hour: Messages or voice by weekday and hour.

Under Health › Audience. Presence cards need the bot's Presence intent and read the whole server.

Presence: Members online, idle, on do not disturb or offline.
Online by hour: The average members online at each hour.
Apps: Time members spent showing an app, such as a game, on their profile.
Segments: Members by activity: New (joined in the last 7 days), At risk (active before, not in the last 14 days), Most invested, Lurker and Active.
Participation: Active members who only wrote, only spoke, or did both.
Members by last activity: Current members by how long ago they last wrote or spoke.
Account age: Current members by the year their Discord account was made.

Under Health › Leaderboards. Press a column to rank by it, and a member or channel to open it in Lens.

Activity: The top 200 members by messages, voice time or reactions.
Levels: Members by level and XP, as /leaderboard ranks them on All time.
Inviters and Invite links: Joins brought in by each member's invites and by each invite link, and how many stayed.
Channels: Every channel with activity in the range, busiest first.
Emoji and Commands: The emoji and slash commands members use most.
Apps: Apps on members' profiles, by time spent.
