I’m sorry if this is a dumb question, I am on my phone and did not check much of the repo. I was thinking of adding a dashboard to my stack, and was thinking about Prometheus + grafana because of versatility but the main con is the complexity. How are the graphs generated on your example? Are they static images generated manually?
