    Example Python code:

     

    try:
    logging.info("Connecting to BIG-IP and pulling statistics...")
    b = bigsuds.BIGIP(hostname=ltm_host, username=user, password=password)
    logging.info("Requesting session...")
    b = b.with_session_id()
except bigsuds.Connecti , detail:
    logging.critical("Unable to connect to BIG-IP. Details: %s" % pformat(detail))
    sys.exit(1)
logging.info("Setting recursive query state to enabled...")
b.System.Session.set_recursive_query_state(state='STATE_ENABLED')
logging.info("Switching active folder to root...")
b.System.Session.set_active_folder(folder="/")

Hi, Yes, that was the magic. Using the ruby icontrol, and using the example filelist-virtual-servers.rb, here are the code changes

 

bigip = F5::IControl.new(bigip_address, bigip_user, bigip_pass, ["LocalLB.VirtualServer", "LocalLB.Rule", "System.Session"]).get_interface   
   sapi = bigip["System.Session"]
   puts "recursive query state = ", sapi.get_recursive_query_state.to_s
 sapi.set_recursive_query_state(state='STATE_ENABLED')
 puts "recursive query state = ", sapi.get_recursive_query_state.to_s

 The rest of the code is left as is, and this produces the entire list.

Also for further reference, used the following links to fill in the background on "folders" with F5.
