Hi,  
I am using logstash http input plugin to get the logs from application team. In kibana i am getting "headers.content\_length" field with numaric value. I did not get what is the exact meaning of "headers.content\_length". Is it application message size in characters or it is size in bytes ? we have disabled ecs\_compatibility in logstash output section.could you please guide me on this?

It's size in bytes. If you use ECS, again will be in bytes, just in another field: [http][request][body][bytes] .

> [headers][content\_length] / [http][request][body][bytes] - Request content length / Size in bytes of the request body. type: long
