Chef Audit Tools

Ohai Chefs!

I was wondering if anyone knew of any tools or scripts out there to do a
complete audit of our chef server to understand what is not being used. I
found knife-audit to gather information about cookbooks being used but I will
need to check all the other pieces (roles, databags). I plan to use search but
before I wrote anything custom I wanted to reach out to the community first.
If I do write something custom I’ll look to open source it.
