Once per day a scheduled task named WebFilteringProxyHistory is run.
This task runs the Diladele.Wfp.Collector.exe process that collects statistics information from the access logs, filters and transforms the log records and stores them as daily CSV files in the statistics storage folder C:\ProgramData\Diladele\WebFilteringProxy\stats.
After statistics storage is updated the Diladele.Wfp.Reporter.exe process builds actual HTML, JSON and CSV files for the Traffic Monitoring UI. These files are stored in C:\ProgramData\Diladele\WebFilteringProxy\reports folder. The files are grouped by day, month, year, user name and domain.
