Welcome! The index isn't created until the first time Filebeat writes to it, so it sounds like the problem you're encountering is that Filebeat is never (successfully) writing anything. There's several reasons this could be happening, for example it might not find any files matching its input pattern, it might be unable to connect to the elasticsearch server, etc. Could you share your configuration (filebeat.yml) and the output logs when you run Filebeat (they're probably in the same place as filebeat, in the logs/ subdirectory)?
