All pages in SourceOptics operate on time series data, and statistics reflect the currently selected date range, as noted in the query string, or the date widget
The date widget allows picking any start and end date, and will constrain the SourceOptics view to that date range. If you did not select a date range, the default range pulled up by SourceOptics is "Unix Epoch" (1970) to today.
The date range is designed to persist with navigation, and is included in any hyperlinks for deep linking to particular graphs
If the date range is not set, the default date range will include everything from 01/01/1970 to today's date. Be sure the SourceOptics administrator has set up either periodic scanning or Webhooks to ensure data is always current.
