# Sysinfo

The *Sysinfo Filter* plugin allows to append system information like fluent-bit version or hostname.

## Configuration Prameters

The plugin supports the following configuration parameters:

| Key                     | Description                                                                     | Supported platform |
| ----------------------- | ------------------------------------------------------------------------------- | ------------------ |
| fluentbit\_version\_key | Specify the key name for fluent-bit version.                                    | All                |
| os\_name\_key           | Specify the key name for os name. e.g. linux, win64 or macos.                   | All                |
| hostname\_key           | Specify the key name for hostname.                                              | All                |
| os\_version\_key        | Specify the key name for os version. It is not supported on some platforms.     | Linux              |
| kernel\_version\_key    | Specify the key name for kernel version. It is not supported on some platforms. | Linux              |

Some properties are supported by specific platform.

## Getting Started

In order 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 fluent-bit version and OS name.

{% tabs %}
{% 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 %}

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

```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 %}
{% 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

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