About Device Discovery
You can discover 12th and later generations of Dell PowerEdge servers with the Plug-in using agent-free method of discovery.
You can opt for SNMP or WS-MAN protocol.
At a time you can only discover a particular Dell device using SNMP or WS-MAN protocol and not both.
You must use Dell Device Discovery Utility to discover Dell devices. If the discovery is successful, then for the discovered
devices, host and service definition files are created. For a device, it is recommended to have a unique host name and IP
address. In Nagios Core, ensure that a host and service definition is not already present for a server that you want to discover.
You can discover devices using any of the following:
● Device’s IP address or FQDN
● Subnet with mask
● File containing a list of device IP addresses or FQDNs
