Use Cases

• Enable iPXE boot scripts to send events via GET query parameters without a request body
• Enable other "GET only" constrained tools to send events

Attempted Solutions

Vector does not emit an event unless there is a request body. iPXEs imgfetch and chain cannot send body. The workaround is to run Nginx or other proxy to translate GET into POST and send to Vector.

Proposal

Allow http_server to emit events when request body does not exist. This would allow a transform to convert the query params into fields.

I realize this is a specialized case but thought I would ask :) Thanks for considering!
