In configure i get only billing tag i need to add AWS info
See this page for information about how to configure the App and Add-on for AWS in Splunk Light. In particular, pay close attention to Step 4 so you can get to the correct configuration page (this is a workaround): http://docs.splunk.com/Documentation/SplunkLight/7.0.1/Installation/GettingstartedSplunkAppforAWS
This should get you on the right track. If you have further issues, please post them here. Thx!
