How to log the number of bytes sent over a websocket?

I am using nginx as a websocket reverse-proxy (this is working fine
BTW). I would like to log the number of bytes sent (and ideally also
received) over a websocket. If I use `$body_bytes_sent` in `log_format`,
the entry in the access_log is always 0. As far as I can tell, a lot of
data went through the websocket, so clearly `$body_bytes_sent` does not
include data sent over a websocket.
I tried to use `$bytes_sent`, but it's just one or two hundred bytes (no
matter how much data is sent over the websocket), so that's clearly just
the HTTP headers. I went through the list of available nginx variables,
but I couldn't find anything for me...
Thanks a lot for any help!
