following beats developer guide I mange to install go. My goal is to change default metricbeat index pattern. I clone git repo, run make command & make update. Command make update created fields.yml file. I add my custom field to fields.yml and run again make update command. After this action I released that fields.yml file is rewritten.
Developer guide mention if you want to change index pattern just run make update command. So what I am doing wrong?
