For example, I want to see which pages I’ve used draw.io macros on, if at all.
Confluence 6.0 introduced a “Macro Usage” admin page for this. You’ll find it under BASE_URL/admin/pluginusage.action.
This page tells you if any user-installed macros are not being used. For those that are being used it shows you how many times they are being used:
Clicking on the link of each macro takes you to a Confluence search of each usage of that macro, so you can view individual items.
Fore more general info on draw.io for Confluence or Jira, please refer to our draw.io webpage.
And some great blogposts! Blog - draw.io
