Hey, i am trying to use fluentd to forward my logs by parsing them into json and output to an http endpoint. I see the fluentd supports an out_http plugin for this. I also wanted to create a unique id (possibly using uuid) in each message i am sending at the forwarder level (not log it myself from application). It would be even better if i can just create that unique id by combining two keys from my json message (their combination is always unique) and base64 encode them. Any tips on how to do within entirely within the fluentd forwarder scope?
