To add or remove component services for a discovered host

Syntax: The following script or syntax helps user to add and remove services that are discovered:

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

addservices=<servicename> --removeservices=<servicename> -output.file=<host file location>

Example:

python dellemc_nagios_discovery_service_utility.py --host=100.98.67.123 --

addservices="NIC,Disk,Controller" --removeservices="StorageEnclosure,VDisks" -

output.file=/usr/local/nagios/dell/config/objects

To add or remove component services for all the hosts or devices that are discovered under given hostgroup

Syntax: Following scripts or syntax helps user to add and remove services under host group:

python dellemc_nagios_discovery_service_utility.py --host=<hostgroup> --

addservices=<servicename> --removeservices=<servicename> -output.file=<host file

Example:

python dellemc_nagios_discovery_service_utility.py --host="Dell EMC Networking" --

addservices="NIC,Disk,Controller" --removeservices="StorageEnclosure,VDisks" -

output.file=/usr/local/nagios/dell/config/objects

NOTE: If there is more than one service with the same component name, then adding and removing service removes all

the repeated component names. Also, --addservices and --removeservices accepts only predefined component

names. For more information, see GUI service name and component name

NOTE: If output.file option is not provided, it takes the value as "<NAGIOS_HOME>/dell/config/objects"

Discovering Dell EMC devices

You can discover all the supported Dell EMC devices using this plug-in.

Prerequisites:

• If you are using SNMP protocol for discovery, ensure that SNMP version 1 or SNMP version 2 are enabled, community string is set

and configured for Dell EMC Servers, Dell EMC Storage devices and Dell EMC Network Switch. For more information see Appendix.

• A secured network connectivity is established between Nagios Core and the device.

• It is recommended that the device must have a resolvable FQDN.

• WSMan is enabled and configured for discovering Dell EMC Chassis devices.

• WSMan is enabled and configured for discovering Dell EMC Servers using WSMan Protocol.

• Redfish is enabled and configured for discovering Dell EMC Servers using Redfish .

To discover Dell EMC devices:

1. Log in to Nagios Core with Nagios administrator privileges.

2. Navigate to the directory <NAGIOS_HOME>/dell/scripts

3. Run the Dell Device Discovery Utility with the option: python dellemc_nagios_discovery_service_utility.py

The script syntax and information on options are displayed. For more information see About Dell Discovery Utility.

Based on your requirement do the following:

• To discover a SNMP device using Host IP address :

python dellemc_nagios_discovery_utility.py --host=<host name or IP address> --

snmp.version=2 --output.file=/usr/local/nagios/dell/config/objects/

• To discover through SNMP or WSMan Protocol/ Redfish REST API using Subnet mask :

python dellemc_nagios_discovery_utility.py --subnet=<subnet with mask> --snmp.version=2

--http.user=<username> --http.password=<password text> --output.file=/usr/local/nagios/

dell/config/objects/
