Hi zbjornson, regarding your question about "Wondering what the free version uses if it doesn't include graphite for dashboarding": the answer is that free version just includes the icingaweb dashboards and not those implemented with grafana.
Also I'd like to clarify a possible misunderstanding: Monitor in a Box does not require that ansible be installed on all the servers. We only require that ansible be installed on the one machine that orchestrates the setup of Monitor in a Box.
