The HTTP input plugin allows you to send custom records to an HTTP endpoint.
HTTP input plugin supports TLS/SSL, for more details about the properties available and general configuration, please refer to the Transport Security section.
The HTTP input plugin will accept and automatically handle gzipped content as of v2.2.1 as long as the header Content-Encoding: gzip
is set on the received data.
The http input plugin allows Fluent Bit to open up an HTTP port that you can then route data to in a dynamic way. This plugin supports dynamic tags which allow you to send data with different tags through the same input. An example video and curl message can be seen below
The tag for the HTTP input plugin is set by adding the tag to the end of the request URL. This tag is then used to route the event through the system. For example, in the following curl message below the tag set is app.log**. **
because the end end path is /app_log
:
If you do not set the tag http.0
is automatically used. If you have multiple HTTP inputs then they will follow a pattern of http.N
where N is an integer representing the input.
The tag_key configuration option allows to specify the key name that will be used to overwrite a tag. The tag's value will be replaced with the value associated with the specified key. For example, setting tag_key to "custom_tag" and the log event contains a json field with the key "custom_tag" Fluent Bit will use the value of that field as the new tag for routing the event through the system.
The success_header
parameter allows to set multiple HTTP headers on success. The format is:
Key
Description

The address to listen on
0.0.0.0
port

tag_key

buffer_max_size
Specify the maximum buffer size in KB to receive a JSON message.
4M
buffer_chunk_size
This sets the chunk size for incoming incoming JSON messages. These chunks are then stored/managed in the space available by buffer_max_size.
512K
successful_response_code
It allows to set successful response code. 200
, 201
and 204
are supported.
201
success_header
