I want to add additional field on filebeat.yml. I want to name it as instancename and the value is the instance name of my aws ec2 instance. How can I add it to the filebeat config?

hi @elkrocks, isn't the aws ec2 instance name already included in the event? Is the goal to rename it?

```auto
processors:

      fields:
        app.instance: 1
      target: ""

```
