I created a test.php the way you suggested. It shows up in the opcache folder. Unfortunately after flushing the opcache it still remains in this folder.

Thank you. After applying this changes, the statistics show up. Still, manually flushing the opcache by clicking the button in your plugin doesn’t work. I get a success message but when I check the directory, it still has all the files in it.
