Hello,

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?

I manage to solve problem on my own. If someone have the same problem procedure is following.

In my case I add fields to module system/process:

1. Git clone
2. Add custom fields to $GOPATH/src/github.com/elastic/beats/metricbeat/module/system/process/\_meta/fields.yml file
3. Run **make** command in metricbeat directory
4. Run **make update** command in metricbeat directory

and that's it 🙂.
