Data Quality Dashboard provides detailed information about the gap between Device Receipt Time from the raw event itself versus the Normalized Event Time. Device Receipt Time represents the moment when the connector received the event, typically close to the time that the event occurred. Normalized Event Time represents the time that the database receives the event. Usually Normalized Event Time is set to the Device Receipt Time, except when the receipt time is not within the boundary of +/-7 days of Recon persistence time. When the Device Receipt Time is not within the boundary, the Normalized Event Time gets assigned to the event. The normalized time removes bad time values from the event data.
Data Quality Dashboard identifies the sources that cause issues with the data. Based on the information analyzed through the Data Quality Dashboard, you can accurately mitigate the problem. This feature also provides history of your data overtime.
