How to get Request size (in bytes) in Gatling?

I want to check what request size are we sending using our Gatling request, is there any option to record that size?

Just like we do using Curl command, curl -w ‘%{size_request}’ . …


Any updates on this? I want to capture the size of my requests using gatling.

Netty sets Content-Length header to outgoing requests that have bodies.

So it should/could be found in the access log
