# Fluent-bit HTTP Input Plugin

### How to integrate Fluent-bit HTTP input plugin with Apica Ascent

#### 1. Introduction

This guide explains how to send logs with the HTTP input plugin to Apica Ascent with Fluent-bit, and how to view them.

#### 2. Configure the HTTP input Plugin in Fluent-bit

Update your Fluent-bit.conf with an input and filter for the HTTP input Plugin:

```
[INPUT]
    Name    http
    Listen  0.0.0.0
    Port    4318
    Tag     ascent_logs
```

```
[FILTER]
    Name   modify
    Match  ascent_logs
    Add    namespace Fluent-bit
    Add    app_name HTTP
```

You could use any free port, port 4318 is not required, it was chosen for this example.

Restart Fluent-bit with `systemctl restart fluent-bit` and check the status with `systemctl status fluent-bit` to verify that it’s running correctly.

{% code overflow="wrap" %}

```

```

{% endcode %}

#### 5. Troubleshooting

[Fluent-bit Troubleshooting](https://docs.apica.io/integrations/list-of-integrations/fluent-bit/fluent-bit-troubleshooting)

If logs are not being sent verify that the port is open and that the server can receive data there.

Verify that the logs are in a format that the HTTP plugin can read such as json.
