I wonder why there are no custom widgets available in the net. Am I missing something?
I just made one for myself showing the detailed CPU activity in a dashboard widget. https://pastebin.com/QJyeifmB
It just needs to be named custom_diag_system_activity.widget.php and placed in usr/local/www/widgets/widgets in the Diagnostics -> Edit File menu
After that its available in the widgets menu.
