Though Icinga retains all the existing features of its predecessor, it builds on them to add many long awaited patches and features requested by the user community. Icinga is an enterprise grade open source monitoring system which keeps watch over a network and any conceivable network resource, notifies the user of errors and recoveries, and generates performance data for reporting.

The authors say that Icinga2 isn't built with automated deployment in mind so it's not very friendly to Ansible, Chef, or Puppet. You can't have Icinga2 realize that you've added a new node to your cluster and automatically provision monitoring for it.
There are no easy guidelines on how to add graphs to your installation. The official documentation mentions installing a plugin but does not give any help on setting it up or actually adding a graph.
Graphs need to be created manually and then added manually to your dashboards. Configuring graphs shouldn't be a full-time job.
All in all, although it's a great product it's not really suitable for a scenario where you expect to add or remove hosts regularly. If you're prepared to spend the time learning how to set it up then I think it will be very valuable, but I suspect that it will be expensive to maintain given the manual nature of the setup.
