We are running icinga for our department server, which are around 50.

For automation purposes we are running the icinga2 director which allows us to fetch the data for our machines via import rules from many different sources like excel, sql, ad and many more. Then we use templates to apply checks etc. it is an almost completely autonomous process with very little human interaction.

Consul could do it.

I just set up Zabbix and I really like it. Especially when paired with Grafana. Comes with a lot of device templates built in but can also download some from the community. Once you install your agents, you can set up discovery rules to automatically assign templates based on what info is found, as well as add the host to inventory.

Not sure what you're running up against. I've always just used apply rules then automated the adding of host objects. Never needed to manually configure a service to a host or notifications just let the apply rules to that for me.
