At the top of your main dashboard display, you will find a usage graph showing levels of both online users (in blue) and flagged activity (in red). The timeframe of the view can be changed with the date range selector to display activity from today, last 3 days, last 7 days, last 30 days, this month (from the beginning of the month to the current day in that month), last month, or any customizable date range you would like. You can also filter this timeline view by sub-OU by selecting a different sub-OU in the drop-down menu in the top-lefthand region of the page.
