  1. Branch off main and merge onto it:
    i. Read journal entries from all boots #41244
    ii. system-logs input ignores folders and add tests #41296
    iii. Add the missing process.name field to System module, Syslog fileset #41354

  2. Package Filebeat

  3. Run the setup command

    ./filebeat setup --modules system
    
  4. Run Filebeat with the following filebeat.yml and modules.d/system.yml

    filebeat.yml

    filebeat.inputs:
      - type: journald
        id: my-journald-normal-input
        tags:
           - journald-input
      - type: filestream
        id: my-filestream-id
        paths:
          - /tmp/flog.log
    
    filebeat.config.modules:
      path: ${path.config}/modules.d/*.yml
      reload.enabled: false
      reload.period: 1s
    
    setup.template:
      settings:
        index.number_of_shards: 1
    
    setup.kibana:
      host: "http://kibana:5601"
      username: admin
      password: testing
      ssl.verification_mode: none
    
    output.elasticsearch:
      hosts: ["http://elasticsearch:9200"]
      preset: latency
      protocol: "http"
    
      username: admin
      password: testing
      ssl.verification_mode: none

    modules.d/system.yml

    - module: system
      syslog:
        enabled: true
        var.use_journald: true
        input:
          tags:
            - from-journald
    
      auth:
        enabled: true
        var.use_journald: true
        var.tags:
          - from-journald

  5. Go to Discover in Kibana, filter by tags: from-journald

  6. Look at fileset.name from the events, there will be only one fileset instead of two, it's random

  7. GOTO 1, you might find a different fileset on 5.
