I have installed Devel module to use xhprof. In devel settings, I have enabled xhprof, but when I load a page, can't see a link to xhprof. I read the source and found this:
drush_log('xhprof link: ' . devel_xhprof_link($devel_run_id, 'url'), 'notice');
Where is this log stored and how can I see it?
