Hi,
SmartEvent only indexes non-connections. By default, Application Control creates a Session log for matching on the rule and SmartEvent index it and you see it in views/reports.
If the application is not found in the list or not recognized for some reason, this probably matched a firewall rule which by default doesn't generate session logs.
You have 2 choices to solve this:
1) Add the application manually as a custom site and create a rule for it with accounting and session logs. This will create URL Filtering logs with accounting information.
2) Go to the matched rule for the traffic and beside accounting, enable session logs for this rule. This will create firewall session logs.
Kind regards, Amir Senn
