last_activity_at

[!NOTE] This data is in {% data variables.release-phases.public_preview %} and subject to change.

The timestamp of a user's most recent interaction with {% data variables.product.prodname_copilot_short %} functionality.

Surfaces

This property is consistent across the following surfaces:

• The CSV report downloaded from the "Access management" page (see AUTOTITLE)
• The AUTOTITLE

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 {% data variables.product.prodname_blog %}.
