The control panel is an integrated place for administrators to manage all their Google Apps services. You can manage user accounts and email lists, customize sharing capabilities within applications, turn services on and off, manage mobile device policies and more. Last week, we added new service activity graphs so Google Apps administrators can see at-a-glance how their users are accessing Google Apps. This information can help customers evaluate the success of Google Apps deployments and scale internal support resources efficiently.

The activity graphs display information about the number of active users in your organization as measured by login activity. We display trend lines showing user activity for the prior 1-, 7- and 30-day periods for Gmail, Google Docs, Google Calendar, and Google Sites.

To view the graphs for your organization, click “View Usage and Reports” under the “Advanced Tools” tab of the Google Apps control panel. We’ll have more service activity data options to share with administrators soon, but in the meantime, you can check out the Reporting API for even more granular data on Google Apps activity within your organization.
