# 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.

#### 3. Verify Logs in Apica Ascent
1\. Log in to **Apica Ascent**
2\. Navigate to **Explore → Logs & Insights**
3\. Look for the namespace and application name specified in the config file\
Example:

#### 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.apica.io/integrations/list-of-integrations/fluent-bit/fluent-bit-http-input-plugin.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
