Yes, just look at the size of the received data in the browser.

Answer 2

as an option on the example of Debian

apt-get install auditd
systemctl start auditd
auditctl -w /var/www/html/index.nginx-debian.html -p arw -k nginx

restart nginx so that it throws resources out of memory,
then it will turn to the web server and look for an event in the log

ausearch -k nginx
