Hi, everyone

I use **Filebeat** in order to send all my data to **Apache Kafka**. Moreover, I use **parameter fields** in order to generate **Kafka Topic dynamically**. Here you are an example:

```auto
filebeat.inputs:

- type: log
  paths:
    - /var/log/mysql.log
  fields:
   service: mysql

- type: log
  paths:
    - /var/log/apache.log
  fields:
   service: apache

filebeat.config.modules:
  path: ${path.config}/modules.d/system.yml
  reload.enabled: false

logging.level: warning
logging.to_files: true
logging.files:
  path: /var/log/filebeat
  name: filebeat
  keepfiles: 4

output.kafka:
  hosts: ["localhost:9092"]
  topic: "%{[fields.service]}"

```

Is it possible to generate **Kafka Topic** dynamically with **Filebeat Modules**?

Thanks in advance,

Regards 🖖

✏ **Update post**

I achieved it by using **processors** :

```auto
filebeat.inputs:

- type: log
  paths:
    - /var/log/mysql.log
  fields:
   service: mysql

- type: log
  paths:
    - /var/log/apache.log
  fields:
   service: apache

filebeat.config.modules:
  path: ${path.config}/modules.d/system.yml
  reload.enabled: false

processors:
- add_fields:
   when:
    equals:
     event.module: system
   fields:
    service: system

logging.level: warning
logging.to_files: true
logging.files:
  path: /var/log/filebeat
  name: filebeat
  keepfiles: 4

setup.template.enabled: false
setup.ilm.enabled: false

output.kafka:
  hosts: ["localhost:9092"]
  topic: "%{[fields.service]}"

```

I think you will have to set 'auto.create.topics.enable=true' on the broker configuration and on the filebeat output define the topic you want to send/create the logs to.
