The Application Blade report in SmartEvent R77.30 shows a different value from other indicators such as Firewall blade's Account tracking report or Wireshark Packet Capture on the client itself.
From the Firewall blade's using Account tracking, I see 5.9MB:
From the Wireshark on the server, I see around 500KB:
From the Application Control log in SmartEvent R77.30, I see 9.12MB:
Why do I see different values when I filtered all the same?(Same source/destination, same port, same time frame)
