How to create a custom index name in Filebeat

***Summary***: Filebeat creates index in default pattern: “filebeat-%{[agent.version]}-%{+yyyy.MM.dd}” -> For example: filebeat-6.7.1–2020.02.11. You can follow the steps mentioned in this article, to have your own custom index name while pushing data from Filebeat to Elasticsearch. Note: I have used Filebeat to push data directly to AWS Elasticsearch.
