Get started

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

[INPUT]
    Name dummy
    Tag test

[FILTER]
    Name sysinfo
    Match *
    Fluentbit_version_key flb_ver
    Os_name_key os_name

[OUTPUT]
    name stdout
    match *

pipeline:
    inputs:
        - name: dummy
          tag: test
    filters:
        - name: sysinfo
          match: '*'
          Fluentbit_version_key: flb_ver
          Os_name_key: os_name
    outputs:
        - name: stdout
          match: '*'

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"}]
