F5 Integration with Cisco Stealthwatch (Lacope) via IPFIX/SFLOW

Has anyone been able to integrate F5 with Cisco Stealthwatch (Lacope)? We are interested in collecting information about the client, virtual server and pool member IPs. I was trying this via an iRule for IPFIX, but ran into issues. Has anyone set this up with sflow as well? If you have any alternatives for logging this SNAT information via a different means, that would be helpful as well.
