FYI I have been writing some session relevance partly inspired by this post and this one: Ansible with BigFix
As well as some of what I have been working on in general.
BigFix External Patch Sites: https://bigfix.me/relevance/details/3019288
display names of bes sites whose(external site flag of it AND exists display name whose(it starts with "Patches for" OR it starts with "Updates for") of it)
Mac & Windows BigFix External Patch sites: https://bigfix.me/relevance/details/3019289

My published set of webreports is very small: https://github.com/jgstew/bigfix-content/tree/master/webreports
But my published set of dashboards is bigger, and most of them could be used as a web report: https://github.com/jgstew/bigfix-content/tree/master/dashboards
I also have been meaning to write up all the different options for testing BigFix Session Relevance.
