Getting Started

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

How to set tag

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. 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.

Example Curl message

curl -d @app.log -XPOST -H "content-type: application/json" http://localhost:8888/app.log
