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 {% data variables.copilot.copilot_chat_short %} in an IDE
• Generating a pull request summary
• Interacting with {% data variables.copilot.copilot_chat_short %} in GitHub
• Interacting with Copilot on a mobile device
• Interacting with {% data variables.copilot.copilot_chat_short %} 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 %}.

Copilot activity report

The Copilot activity report shows user activity data for an organization or enterprise.

Data in the report refreshes automatically every 30 minutes.

Fields

Field	Description
report_time	UTC timestamp when the report was generated
login	GitHub username of the Copilot user
last_authenticated_at	UTC timestamp of the user's most recent authentication
last_activity_at	UTC timestamp of the user's most recent Copilot interaction
last_surface_used	The Copilot feature used most recently: IDE: Editor name and version (e.g. "VS Code 1.89.1") GitHub.com: Feature name (e.g., "Copilot Chat") Unspecified: When IDE details are unavailable or no recent activity exists

Retention period

Activity and authentication data are retained for a rolling 90-day period, consistent with the last_activity_at field.

Included features

The activity report provides visibility into usage of all generally available (GA) GitHub Copilot features in the IDE, on GitHub, in GitHub CLI, and on GitHub Mobile.

IDE features

• Inline suggestions
• {% data variables.copilot.next_edit_suggestions_caps %}
• {% data variables.copilot.copilot_chat_short %}
• Agent mode
• {% data variables.copilot.copilot_edits_short %} in VS Code

GitHub features

• {% data variables.copilot.copilot_chat_short %}
• {% data variables.copilot.copilot_coding_agent %}
• Copilot for Docs
• {% data variables.copilot.copilot_for_prs %}
• {% data variables.copilot.copilot_code-review_short %}

Limitations

There is a possibility that {% data variables.product.github %} lacks consistent telemetry from some third party IDEs outside of VS Code (such as JetBrains and Xcode). Users should ensure they're running the latest version of their IDE.

The activity report may exclude usage of {% data variables.product.prodname_copilot %} features that are not yet generally available (GA). Currently, the following features are not fully recorded:

• {% data variables.copilot.copilot_spaces %}
• Copilot Spark
