LTM request logging

yes, I think you would rather using tcpdump for just check packet

and you have to configure ssl certtificate on virtual server  if you want to remain log 

and then configure below irule

when HTTP_REQUEST {
set vip [IP::local_addr] set uri [HTTP::uri]

log local0.info "Client [IP::client_addr]:[TCP::client_port] connected to VS ($vip)for URI $uri"
}
