List,

A general question:

   Can nagios core be used for   HCI nodes and other nodes which are installed with Type1 hypervisors ? ( Eg:  ESXi  hypervisor doesn't have an OS to install the nagios on to it.. as it a bare metal hypervisor . )

How do people monitor these base machines with configurable alerts/notifications to email, and mobile phones  of people who manage ?'
