You would require to capture the traffic using wireshark or any other sniffer to get the session ID details. You can use the following commands on F5 to get the packet captured and analyse it using wireshark:-

tcpdump -s0 -ni 0.0:nnnp -w /var/tmp/test_app.pcap

(test_app - is the filename which you can change depending upon your testing). You can then copy this file from your host F5 to your computer using SCP and then analyse it.

I would suggest, first to enable cookie persistence and then check the load balancing, whether it meets your requirement or not.There are chances that it can be supported.

The persistence irule will depend upon the kind of session ID that gets generated. Let me know the format and I shall try to create one for you.
