Hi folks,

I was thinking of picking up [this issue](https://github.com/elastic/beats/issues/11975) as it's a problem that we ran into and will likely need to fix soon. Is anyone already working on it or is there anything I should bear in mind when altering the fields?

I believe this should be quite simple, changing the fields.yml and associated docs where the relevant fields are defined. Any recommendations beyond that?

Many thanks,

Alexander

That's great @easkay!

Sounds like your approach is correct. After doing the change you will need to run `make update` in the development folder, so fields.yml gets translated to our code to be used by Metricbeat

Please let us know if you find an issue, feel free to open a PR for discussion and help request

Best regards

Thanks very much @exekias! I also gave the docs a read and they were very helpful too, mentioning to run `make update` as well as a couple of others.

~~Will hopefully have the PR in soon.~~ PR is here: [https://github.com/elastic/beats/pull/12476](https://github.com/elastic/beats/pull/12476)
