Redirect 404 errors to a separate log file

Server NGINX
1

I have been trying for a whole day to figure out how to redirect 404
errors
to a separate log file. I managed to do this in the server directive:

error_page 404 = @404;
location @404 {
error_log /var/log/nginx/404.log;
}

This does write all 404 errors to 404.log, but the problem is that it
also
writes these errors in the default error.log, and I don’t want that. I
want
404 errors to be writtent to only into the 404.log.

Do you have an idea how to do this?

Errors to error_log are logged once they happen, so you can’t
configure separate error_log to log specific errors (in contrast
to access_log).

However you may control whether to log “not found” errors or not -
there is configuration directive “log_not_found” for this, see
Module ngx_http_core_module.
