Hi  If you have SSL offloading done on F5 vServer i.e. client SSL configured, then F5 can decrypt the traffic and re-encrypt it if required while forwarding it to the pool members. If you want to see the

connections/hits passing through the F5 then there are several ways like-

  1. seeing active server and/or client side connections using cli command show sys connection xx
  2. Seeing hits on the vServer and backend pool members
  3. logging required requests traffic using iRule
  4. tcpdump etc.

How do I read the traffic .. ex. Phone number i want to see from client going to server
