With that in mind, I wanted to look at GitHub's Community Health measure of the repositories I'm responsible for. You can view each repo's community page separately through the web interface (look under "Insights") but that's not especially scalable if you have a lot of projects to track.
I've tried to write down and link to the stuff I found useful along the way with this project, in case it helps you too. Well, no, really so I can come back to it next time I'm using one of these!
