Help me - How can I configure firebeat to read log files from log folder

[Huy_Hoang_Le]

I have an app that write log to .log file to a log folder that mounted from container to host.

I'm very new to ELK overall so I want filebeat to read .log files generated in that log folder. Here is my filebeat config file

logging.level: debug
logging.to_files: true
logging.files:
  path: /var/log/filebeat
  name: filebeat
  keepfiles: 7
  permissions: 0600
  
filebeat.config:
  modules:
    path: ${path.config}/modules.d/*.yml
    reload.enabled: false

filebeat.inputs:
- type: log
  paths:
    - /media/HDD10TB/log/*.log

processors:
# The following example enriches each event with the machine's local time zone
# offset from UTC.
#      
- add_locale:
      format: abbreviation
#
# The following example enriches each event with host metadata.
#      
- add_host_metadata: ~    

output.logstash:
   hosts: ["logstash-01:5400"]  

when I go to index management on Kibana I see 0 Docs count. What is the problem here? How can I solve it.?
Thanks

Here is my docker-compose.yml

Hello and welcome,

If you are running filebeat in a docker container, the path with your logs needs to be accessible to your container.

In your filebeat you have this configuration:

filebeat.inputs:
- type: log
  paths:
    - /media/HDD10TB/log/*.log

But in your docker compose you are not bind mounting the /media path to your filebeat container.

    filebeat:
        user: root
        container_name: filebeat-01
        command: --strict.perms=false
        volumes:
            - filebeat.docker.yaml:/usr/share/filebeat/filebeat.yml:ro
            - /var/lib/docker/containers:/var/lib/docker/containers:ro
            - /var/run/docker.sock:/var/run/docker.sock:ro

You need to make the log path accessible to your container, this is related to docker, not filebeat itself.

Thank you very much for your response. I will try to mount the log file to docker and will let you know if it works

Hi, there is logging.level line in filebeat.yml so is there a config to track all log level including Info, Error, Debug and Critical ?
