Trying to get stats on Load Balancer using iControl.System.Connections

Trying to get information about load balancer similar to info that can be found under Overview/Traffic summary but using iControl so I can log the info. I can connect and other methods work but I can't get get_all_active_connections() to work, it always throws error: Operation Failed, primary_error_code : 16908292, error_string: Unable to complete request. Any help appreciated, thanks.
