In my reports, I don't see any data for uncategorized or "passed" traffic.

Depending on which version of the reporter you are running, Uncategorized sites might be toggled OFF.

To check this setting, log into the Webclient on port 8080, go to Settings > Default Options.

If "Hide Uncategorized Category" is checked, be sure to uncheck it to be able to view Uncategorized traffic.
