Part of our security includes locking down the list of devices that are allowed to send data to your inputs. If you have a dynamic environment, however, the list of devices will likely change on a frequent basis. To help with this, we have a python script that will authenticate devices without requiring that you work through the Loggly user interface. Use this script with your configuration tool (e.g. puppet/chef) to auto-authenticate devices when you spin up a new instance.
