To set up multiple input and output sources, you need to edit the configuration file of Filebeat. The default location of Filebeat’s configuration file is /etc/filebeat/filebeat.yml.

Here is an example of configuring multiple input and output sources:

  1. Open the configuration file for Filebeat.
sudo nano /etc/filebeat/filebeat.yml
  1. Set up multiple input sources.
filebeat.inputs:
- type: log
  paths:
    - /var/log/syslog
  fields:
    log_type: syslog
- type: log
  paths:
    - /var/log/nginx/access.log
  fields:
    log_type: nginx_access

The above example specifies two input sources: /var/log/syslog and /var/log/nginx/access.log. Each input source uses “type: log” to specify the type as a log file, and uses “paths” to specify the file path. “fields” is used to add custom fields for each input source.

  1. Set up multiple output sources:
output.elasticsearch:
  hosts: ["localhost:9200"]

output.logstash:
  hosts: ["localhost:5044"]

The above examples have configured two output sources: Elasticsearch and Logstash. You can choose either one or use both according to your needs. Keep in mind that each output source requires configuring the hosts parameter.

  1. Save and close the file.
  2. Restart Filebeat to apply the new configuration:
sudo systemctl restart filebeat

The steps for configuring multiple input and output sources in Filebeat have been outlined. Depending on your needs, you can add more input and output sources as necessary.
