In the DLP Enforce console, you can see the traffic details for each server, but the View option on the Traffic page doesn't show specific dates.
It shows Today, Yesterday, Last 7 days, Last 30 days, Last 365 days, and All Dates.
If you select Last 7 days it gives the total numbers for the 7 days.
What about last Sunday or any other specific day?
If you hover over the graph for each day, the details for those days should be available.
You cannot select or see data for individual days.
Feature request ISFR-3463 has been submitted to add more granularity to the Traffic page.
If you want to be added to that request, open a case with Support and provide this KB number.
