last_activity_at

Примечание.

The timestamp of a user's most recent interaction with Copilot functionality.

Surfaces

This property is consistent across the following surfaces:

Calculation

The following interactions count as activity:

  • Receiving a code suggestion in an IDE
  • Chatting with Copilot Chat in an IDE
  • Creating or updating a knowledge base
  • Creating a pull request summary
  • Interacting with Copilot Chat in GitHub
  • Interacting with Copilot on a mobile device
  • Interacting with Copilot Chat for CLI

The tracked events come from both client- and server-side telemetry, ensuring the timestamp is durable if network conditions affect client-side telemetry.

Processing new telemetry events and updating a user's last_activity_at date can take up to 24 hours. Users must have telemetry enabled in their IDE for their usage to be reflected in last_activity_at.

Retention period

  • The retention period for last_activity_at data is 90 days. This cannot be modified.
  • After 90 days of no new activity, a user's last_activity_at value is set to nil.

For more information, see Updating retention period for last_activity_at values on the Copilot user management API to 90 days on the GitHub Blog.
