# Collectd

The *Collectd* input plugin lets you receive datagrams from the `collectd` service.

## Configuration parameters

The plugin supports the following configuration parameters:

| Key        | Description                                                                                                                         | Default                        |
| ---------- | ----------------------------------------------------------------------------------------------------------------------------------- | ------------------------------ |
| `Listen`   | Set the address to listen to.                                                                                                       | `0.0.0.0`                      |
| `Port`     | Set the port to listen to.                                                                                                          | `25826`                        |
| `TypesDB`  | Set the data specification file.                                                                                                    | `/usr/share/collectd/types.db` |
| `Threaded` | Indicates whether to run this input in its own [thread](https://docs.fluentbit.io/manual/4.1/administration/multithreading#inputs). | `false`                        |

## Configuration examples

Here is a basic configuration example:

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

```yaml
pipeline:
  inputs:
    - name: collectd
      listen: 0.0.0.0
      port: 25826
      typesdb: '/user/share/collectd/types.db,/etc/collectd/custom.db'

  outputs:
    - name: stdout
      match: '*'
```

{% endtab %}

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

```
[INPUT]
  Name         collectd
  Listen       0.0.0.0
  Port         25826
  TypesDB      /usr/share/collectd/types.db,/etc/collectd/custom.db

[OUTPUT]
  Name   stdout
  Match  *
```

{% endtab %}
{% endtabs %}

With this configuration, Fluent Bit listens to `0.0.0.0:25826`, and outputs incoming datagram packets to `stdout`.

You must set the same `types.db` files that your `collectd` server uses. Otherwise, Fluent Bit might not be able to interpret the payload properly.
