how to check which clients are generating most traffic to a particular VIP?

Hi,   i have mainly worked riverbed load balancers so new to F5s. I am troubleshooting an over subscription issue with one of the web services and struggling to check who's generating more traffic...

Hi clients are not behind a proxy. they call this VIP which has webservers in a pool attached to this VIP.

 

Clients --> VIP->Webservers

    Thanks for the details .

    we can achieve this by using tcpdump command during the peak session.

    tcpdump -nn dst host VIP_IP and dst port VIP_PORT -w /var/tmp/test.pcap

    Check the output in wireshark and analysis it. text hope you will get some results.
