NOTE: If the other Dell EMC discovery utility parameters are not passed, the command will run with default values.
NOTE: Ensure that the Dell EMC device is discovered either using IP address or FQDN and not both at a given
instance.
4. By default, Dell EMC Server is discovered using Redfish Protocol. If the WSMan protocol parameters are not passed in the command,
the discovery will happen through SNMP. Based on your requirements, the value of --prefProtocol can be changed.
Dell EMC Servers can be discovered through either WSMan or Redfish or SNMP using the below commands:
• To discover using WSMan Protocol using File Path :
python dellemc_nagios_discovery_utility.py --file=<absolute file path> --prefProtocol=2
--http.user=root --http.password=calvin --output.file=/usr/local/nagios/dell/config/
objects/
• To discover using Redfish REST APIs using File Path:
python dellemc_nagios_discovery_utility.py --file=<absolute file path> --prefProtocol=3
--http.user=root --http.password=calvin --output.file=/usr/local/nagios/dell/config/
objects/
• To discover using SNMP using File Path:
python dellemc_nagios_discovery_utility.py --file=<absolute file path> --prefProtocol=1
--snmp.version=2 --output.file=/usr/local/nagios/dell/config/objects/
5. Once the discovery utility script is run, verify the Nagios configuration by running the command <NAGIOS_HOME>/bin/nagios -
v /<NAGIOS_HOME>/etc/nagios.cfg.
NOTE: If --enable.log parameter is not passed, the logs will not be created.
NOTE: If the --enable.log parameter is passed, but the --logLoc value is not defined, the logs will be created in the
default location <NAGIOS_HOME>/var/dell
6. Ensure that no errors are present and then restart Nagios Core by running the command service nagios restart.
After completion of discovery:
• Dell EMC device Host definition and its service definitions are created in the Nagios server and this is subsequently used for monitoring
the Dell EMC devices.
The discovered Dell EMC devices and their services are displayed in the Host view and the Services view in the Nagios Core console.
Wait for the scheduled service to complete for the service details to be displayed.
• The discovered Dell EMC devices are displayed in the Map view in the Nagios Core console.
