# Send Logs to the Platform

{% hint style="info" %}
**Prerequisites:** To send logs to the logging platform, you must have the following:

* A `Ready` pipeline instance to obtain the `tcpAddress` or `httpAddress`.
* A [<mark style="color:blue;">key</mark>](https://docs.ionos.com/sections-test/guides/observability/logging-service/api-how-tos/obtain-key) that you already obtained.
* Fluent Bit log agent installed in your platform. For more information, see [<mark style="color:blue;">Getting Started with Fluent Bit</mark>](https://docs.fluentbit.io/manual/installation/getting-started-with-fluent-bit).
  {% endhint %}

Based on your infrastructure—whether it uses Kubernetes, Docker, or Linux Systemd—you may follow different instructions to set up and install Fluent Bit. However, ensure that the Fluent Bit's output configuration contains the following:

* A log server endpoint is either a `tcpAddress` or a `httpAddress`, based on your log source.
* A `Shared_Key` is required for authentication.
* The `Tag` that you defined while creating the pipeline.

Here is an example of a Fluent Bit configuration that needs an endpoint, tag, and a key:

```editorconfig
[OUTPUT]
    Name            forward
    Match           *
    Port            9000
    Tag             <TAG>
    Host            <TCP_ENDPOINT>
    tls             on
    Shared_Key      <KEY>
```

{% hint style="warning" %}
**Warning:** The port must be set to **9000** if you are using a TCP protocol.
{% endhint %}

## Troubleshooting

Fluent Bit can be configured to expose more verbose logs for troubleshooting purposes.

```editorconfig
[OUTPUT]
    Log_Level      debug
```
