Hi,

I have an issue I am strugling with since some times and I can't find anything on this forum.  
I hope you'll be able to help me since i'm desperate.

I am trying to drop some fields from the apache2 module of filebeat.  
See below an example of my module config (/etc/filebeat/modules.d/apache2.yml):

```auto
    - module: apache2
      access:
        enabled: true
        var.paths: ["/var/log/api_front-access.log"]
        processors:
            - drop_fields:
                fields: ["access.user_agent.device"]
      error:
        enabled: false
        var.paths: ["/var/log/api_front-error.log"]

```

Thank you!! 🙂

Modules do not parse content in beats, but in Ingest Node. The file defining the ingest node pipeline can be found in the filebeats module directory [apache2/access/ingest/default.json](https://github.com/elastic/beats/blob/master/filebeat/module/apache2/access/ingest/default.json).

One can modify the pipeline definition. But so to not loose changes to the module when updating filebeat, better copy the apache2 module definition as is into `myapache2` and modify the ingest node definition to remove the `access.user_agent.device` field.

One can configure the path of module definitions in filebeat. Alternatively to cloning the module, copy the definitions, change the path to your copy, adapt the `apache2` module. Afterwards remove the old apache2 access ingest pipeline so to force a reinstall of the pipeline.

Hi,

Thank you for your response.

Ok I will try this solution.  
I thought that this was possible because I did the same thing in metricbeat system module and it worked perfectly.
