# 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](/manual/4.1/administration/multithreading.md#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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.fluentbit.io/manual/4.1/data-pipeline/inputs/collectd.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
