The historic data mode displays the graphs based on the older events that are stored in offline aggregator. The data is displayed for the time duration that administrator specifies in the Analytics Dashboard scheduler.
When an administrator requires the historic data, they can specify the duration in the Scheduler page, then Analytics Server generates an analytic graph report that is used for displaying the graphs with historic data. The Administrator can delete the data manually or specify the duration after which the analytic report must be deleted from the scheduler.
You can view these graphs from the Scheduler screen. For more information about using Scheduler, see Section 19.9.6, Viewing Historic Data.
To return to the default dashboard to view the real-time data, you can click the Goto saved default icon. For information about the actions that you can perform on the dashboard, see Section 19.9, Managing Analytics Dashboard.
