We use Icinga2 and telegraf too. We have Icinga check the global (cluster) health, and besides that, have icinga monitoring plugins running on the nodes checking node specific (ceph) health. Every node checks if the local daemons are running like they should. Global Ceph health could end up in "HEALTH_OK", because it might recover the data on another OSD for example. This leaves your cluster in a less than optimal state (one OSD less) than it should be. Local node monitoring will inform you in this case (i.e. it expects x OSD daemons running locally). Gr.
