Traverse has an integrated NetFlow collector which is pre-installed, but disabled by default.
Login to Traverse as superuser, or an equivalent user.
Navigate to the Superuser > Global Config > Netflow Collector page.
Choose the DGE or DGE extension you wish to add a netflow collector on, and select Update.
Enable the netflow collector, then choose a device from your list of network devices. Only routers, switches, and firewalls can be used as flow sources. Choose the host to allow flow data from. This allows you to send flow data from the loopback interface, or from a different IP than the one provisioned in Traverse). Choose the port, and the protocol that Traverse will accept. Additionally, you can specify the network that is "inside" of this device, so that Traverse can categorize the data from an internal/external standpoint.
Press the Save button when you are done. Traverse will respond with the following prompt:
Choosing Yes, Apply Now will immediately write the new configuration out to the flow collector, and re/start the flow collection subsystem. Choosing No, Defer For Later will save your configuration, but not apply it to the DGE extensions nor re/start any flow services.
