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.

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: '*'

fluent-bit.conf

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"}]
