About device discovery

You can discover the supported Dell EMC devices with this plug-in in the Nagios Core console. The monitoring protocols for the supported

Dell EMC devices are as follows:

• Dell EMC Servers are discovered using SNMP or WSMan protocol or Redsh REST APIs.

• Dell EMC Chassis are discovered using WSMan protocol.

• Dell EMC Storage and Dell EMC Network Switches are discovered using SNMP protocol.

NOTE: For discovery using Redsh REST APIs, iDRAC rmware version should be 2.50.50.50 or above.

NOTE: For Dell EMC server discovered through Redsh, if the iDRAC rmware version is 2.50.50.50, the attribute values of

OSName, OSVersion, ChassisServiceTag, GroupManager and GroupStatus will be shown as Not available

You must use Dell EMC Discovery Utility to discover Dell EMC devices. If the discovery is successful, then for the discovered devices,

host and service denition les 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 denition is not already present for a Dell EMC device that you want to discover.

You can discover devices using any of the following:

• Device IP address or FQDN

• Subnet with Mask

• File Containing a list of device IP addresses or FQDNs or Subnet with Mask

•

NOTE: At a time you can discover a Dell EMC Server using SNMP or WSMan protocol or Redsh REST APIs. To rediscover a

server previously discovered through SNMP protocol with WSMan protocol or Redsh REST APIs or vice versa, run the Dell

EMC Discovery Utility option along with the value of the desired protocol.

NOTE: If a server was discovered using SNMP, but you want to discover the same device using WSMan protocol, navigate to

<NAGIOS_HOME>/dell/scripts, and run the following Python commands:

For example:

To discover a SNMP device through WSMan Protocol using Host name details:

python dellemc_nagios_discovery_service_utility.py --host=<host name / IP address> --

prefProtocol=2 --http.user=root --http.password=calvin --output.file=/usr/local/nagios/

dell/config/objects/

<NAGIOS_HOME> is the installed location of Nagios Core and by default, the location of <NAGIOS_HOME> is /usr/local/nagios.
