I'm creating a new Beat from the Developer Guide (https://www.elastic.co/guide/en/beats/devguide/master/index.html). The Beat is functioning well, but I would like to do some final configuration. I've looked all over and have found nothing about how to do this. I'm mainly interested in how to change the index name template the Beat is using and how to have the Beat supply information for Elasticsearch to create an index alias for the indexes the Beat will be writing to.
The Beat is always creating indexes named <beatname>-7.0.0-alpha1-yyyy.MM.dd and there is no alias. What do I need to do to override the index name template and create an alias? Thanks.
