Get started

To start filtering records, you can run the filter from the command line or through the configuration file.

The following configuration file is to append the Fluent Bit version and operating system name.

{% tabs %} {% tab title="fluent-bit.yaml" %}

pipeline:
  inputs:
    - name: dummy
      tag: test

  filters:
    - name: sysinfo
      match: '*'
      fluentbit_version_key: flb_ver
      os_name_key: os_name

  outputs:
    - name: stdout
      match: '*'

{% endtab %} {% tab title="fluent-bit.conf" %}

[INPUT]
  Name dummy
  Tag test

[FILTER]
  Name sysinfo
  Match *
  Fluentbit_Version_Key flb_ver
  Os_Name_Key os_name

[OUTPUT]
  Name stdout
  Match *

{% endtab %} {% endtabs %}

You can also run the filter from command line.

fluent-bit -i dummy -o stdout -F sysinfo -m '*' -p fluentbit_version_key=flb_ver -p os_name_key=os_name

The output will be something like the following:

[0] dummy.0: [[1699172858.989654355, {}], {"message"=>"dummy", "flb_ver"=>"2.2.0", "os_name"=>"linux"}]
