5 Dell EMC Configuration Wizard You can discover Dell EMC devices using the Dell EMC Configuration Wizard. This wizard takes you through a series of configuration steps where you provide appropriate input required to discover the hosts and associate them with their respective services. The Dell EMC plug-in validates the inputs at the end of each step before proceeding to the next step and displays appropriate message prompts or summary.
Communication Parameters The supported Dell EMC devices can be discovered through either SNMP or WSMan protocol or Redfish REST APIs . Based on the desired protocol, you must configure the communication parameters. By default, WSMan protocol is selected. Ensure that you select the Preferred protocol to discover Dell Agent-Free server appropriately. Selecting or not selecting this field does not have any impact while discovering Dell EMC Chassis or Storage arrays or Network Switches.
Configuration Parameters You can set the values for the configuration parameters based on your requirements. Table 15. Configuration parameters Configuration Parameters Parameter Name Default Value Description Warranty URL https://api.dell.com/support/ assetinfo/v4/getassetwarranty/ URL to fetch warranty details. Warranty Critical Days 10 Number of days left before warranty expires. Warranty Warning Days 30 Number of days left before warranty expires.
● Retry Interval - Used to define the number of "time units" to wait before scheduling a re-check of the service. ● Max Check Attempts - Used to define the number of times that Nagios will retry the service check command if it returns any state other than an OK state.
