To run the Dell Device Discovery Utility, browse <NAGIOS_HOME>/dell/scripts, and run the following Python command:

python dellemc_nagios_discovery_service_utility.py -h

All the available Dell EMC device discovery utility options are displayed.

Table 1. Dell EMC Device Helper Utility optionsThis table lists the Dell EMC Device Helper Utility options.
Options Description
-h Displays the list of available options
--host Host IP address or Host Name that are discovered.
--File Provides a filename with path containing the IP addresses/Hostname/Subnet with mask, which is separated by new line.
--subnet To get the Subnet with mask.
--all This option is used to display detailed services.

If --all parameter is added, the result displays all the detailed services. By default, only basic services are displayed.

--prefProtocol PrefProtocol used for monitoring Allowed options are 1 (SNMP), 2 (WSMan) and 3 (Redfish). This value is optional.
NOTE This parameter is applicable only for Dell EMC servers. By default, Server is discovered using Redfish Protocol if Redfish parameters are passed. Else the discovery happens through SNMP if SNMP parameters are passed.
--output.file This displays the location where the host file is created in .cfg format.
NOTE If the option is not provided, it takes <NAGIOS_HOME>/dell/config/objects location for creation of host file.
--logLoc This parameter takes the log location from the user.
NOTE If this attribute is not passed, the logs are created in the default location /<NAGIOS_HOME>/var/dell
--snmp.version Version of SNMP protocol. Allowed options are 1 (SNMP v1)., 2 (SNMP v2c)
--snmp.community Community string for SNMP communication

--snmp.timeout SNMP timeout values (in seconds) allowed values are [1-1440]. Default value is 3.
--http.user WSMan/REST/Redfish authentication username
NOTE For monitoring purpose, it is recommended to have read-only permission for the users.
--http.password WSMan/REST/Redfish authentication password
--http.timeout WSMan/REST/Redfish timeout (in seconds) allowed value is [1-1440]. Default value is 30.
--http.retries WSMan/REST/Redfish retries count allowed value is [1-10]. Default value is 1.
--http.port WSMan/REST/Redfish port details Allowed value is [1-65535]. Default value is 443.
--enableLog To enable or disable the logs.

--force --force rewrites the config file.
--warranty.criticalDays Warranty critical days Allowed value is [1-365]. Default value is 10.
NOTE The value of Warranty critical days should be less than Warranty warning days.
--warranty.warningDays Warranty warning days Allowed value is [1-365]. Default value is 30.
--nagios.type Decides the output format of the host file Allowed options are 0 for .cfg format and 1 for .xml format.

Default values are 0.

--addservices Adding services for monitoring at host or host group level.
--removeservices Removing services from monitoring at host or host group level.
--hostgroup Adding or removing services at host group level
--excludeinstance To exclude instance of a component during monitoring
--service Used along with excludeinstance while providing component name
--listservices To list services of host or multiple hosts(using -File,--subnet) or hostgroup
Table 2. Dell EMC Device Helper Utility Mandatory ParametersThis table lists the mandatory parameters of the Dell EMC Device Helper Utility command.
--host

These parameters define the value of the Dell EMC device to be discovered.

--filename
--subnet
--snmp.version

This parameter is mandatory for a Dell EMC device that is discovered through SNMP.

--http.user

This parameter is mandatory for a Dell EMC device that is discovered through WSMan/Redfish.

--http.password

This parameter is mandatory for a Dell EMC device that is discovered through WSMan/Redfish.

--output.file

This displays the location where the host file is created in .cfg format.

Based on the options you selected during discovery, the following services are associated with that host:

  • If you run the Python command python dellemc_nagios_discovery_service_utility.py without the --all option, then only the basic services are created by default and displayed in the user interface under Services.

    NOTE SNMPTT must be configured for you to be able to receive traps.

  • If you run python dellemc_nagios_discovery_service_utility.py with the --all option, detailed services are created as listed in the table below, and are displayed in the Nagios Core console under Services:
