I'm using ES recently. After having read several posts, I don't see how to use the best method to import datas from a text file in an index. I need to import this file each month and update the index with the new datas. For the moment, I tested a manual import in the data visualizer in Kibana. It's working, but I need to set specific settings and build a periodic task.
What is the best method for this task? Can I use the ES UI for this ? Or do I create a script (PHP) ?
Can you give me methods and information to understand the process?
