    FortiWeb # diagnose debug trace tcpdump interface port1

    FortiWeb # diagnose debug flow filter client-ip 10.0.8.104

    FortiWeb # diagnose debug flow filter flow-detail 7

    FortiWeb # diagnose debug trace report start

  3. Initiate HTTP request from this client (10.0.8.104) to the virtual server.
  4. Stop collecting the information with the command below after some time:
  5. FortiWeb # diagnose debug trace report stop
