I have Splunk Light on Windows and the Universal Forwarder on Raspberry. According to docs, I need to create a server class for receiving data. The admin UI does not give me an option to do so.
How do I configure SL to receive data from a UF?
For more details on the process that @jterry refers to, see the topics in the Getting Data In chapter of the Splunk Light User Guide. A good starting topic is http://docs.splunk.com/Documentation/SplunkLight/6.4.0/GettingStarted/Aboutaddingdata
The distinction between a forwarder & a deployment client is blurred in SL. For forwarding all you need to do is open/listen to a port on the server & tell the forwarder to send data there. (splunk add forward-server ...). In the latest release, it's recommended that all forwarders also be deployment clients (splunk set deploy-poll ...). This ties into the server class concept where forwarders (configured as deployment clients) can be managed in groups.
