Hi team, we have configured a Palo Alto Firewall to send Netflow to a Filebeat.

We are seeing all events right, except that the "User-ID" Netflow field (value 56702) its not shown.

We have replaced the Filebeat with a Logstash, and with it we are seeing the "User-ID" Netflow field is mapped on the "netflow\_user\_id" Elasticsearch field.

Is there any way to configure the Netflow Filebeat Input to collect it? Or it's an issue that must be fixed in the code?

Thanks!

The netflow input in Filebeat has support for [custom field definitions](https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-input-netflow.html#custom_definitions). For example:

```auto
filebeat.inputs:
- type: netflow
  max_message_size: 10KiB
  host: "0.0.0.0:2055"
  protocols: [v5, v9, ipfix]
  expiration_timeout: 30m
  queue_size: 8192
  custom_definitions:
  - /etc/filebeat/netflow-application-specific-fields.yml

```

`/etc/filebeat/netflow-application-specific-fields.yml`:

```auto
346:
- :uint32
- :privateEnterpriseNumber
56701:
- :string
- :app_id
56702:
- :string
- :user_id

```
