I am working with AWS FireLense using Fluent Bit to forward logs from ECS. There is a parsers file with a JSON parser, and the inputs are dynamically generated by the AWS FireLense image. The generated inputs are both of type forward.
Outside of the AWS specific stuff, I know that some input plugins like Tail have the ability to assign a parser. How do forward, dummy, tcp, etc., know which, if any, parser to use?
For reference, here is a link to a sample partial config section https://github.com/aws-samples/amazon-ecs-firelens-under-the-hood/blob/mainline/generated-configs/fluent-bit/generated_by_firelens.conf
