How can I generically get all LB objects & attributes via iControl?

If you are looking for a serialized format of the bigip configuration, you can directly download the /config files from the BigIP. Let the product developers do your work for you!

 

 

Look at System::ConfigSync. You will want to first use save_config which will serialize the config to files in the control plane OS's file system. Then you can list the files with get_configuration_list. From that list you can use download_file to pull them through iControl.
