I found a simple way to trigger a message to the error log, so I
thought I’d share it in case someone also has use for this.

If the root of your site is /foo/mysite/ create an empty directory
there, e.g. /foo/mysite/xyzzy

Do *not* create any index file there, e.g. no index.html or index.php

Now you request that URL via any client of your choice, e.g. curl:


That request will trigger a message to the error log that looks like

2020/06/20 07:30:04 [error] 694#694: *835 directory index of
  "/foo/mysite/xyzzy/" is forbidden, client:, server: ,
  request: "GET / HTTP/1.0"
