NOTE: While configuring the Warranty information parameters, ensure the following: • Provide positive numeric values only. In case any value other than a numeric is provided, the warranty information severity will be in the Unknown state while the warranty details will be displayed. • Do not change any of the other key values in the dell_pluginconfig.cfg file other than the numerical values.
9 Removing Dell EMC devices You can remove a Dell EMC device that you do not want to monitor. 1 Navigate to /dell/config/objects, and delete the corresponding .cfg file. 2 For completing the removal of the Dell EMC device, restart the Nagios Core services by running the following command: service nagios restart.
10 Knowledge Base (KB) messages for the generated alerts You can get more information about the SNMP alerts generated by the discovered Dell EMC devices from the KB messages for that device in the Nagios Core console. Viewing KB messages To view the KB messages for an SNMP alert generated by a discovered Dell EMC device complete the following steps: 1 Log in to the Nagios Core console. 2 In the left pane, click on Services under Current Status.
11 Troubleshooting This section lists the problems that you may encounter while using the Dell EMC OpenManage Plug-in for Nagios Core and their workarounds. Ensure that you meet the requirements, or perform the steps listed in this section. SNMP traps are not received from the Dell EMC devices in the Nagios Core Console for Ubuntu setup. Resolution :Replace #!/bin/sh to #!/bin/bash in /libexec/eventhandlers/submit_check_result and then, restart SNMPTT and Nagios service.
The discovery script is failing to execute 1 The discovery script has appropriate permissions. Recommended: Nagios Administrator. 2 The appropriate arguments are provided while running the script. The discovery script is not creating the host and service definition file for IPv4 or IPv6 addresses or hosts when the protocol selected is 1 (SNMP) 1 Net-SNMP is installed. 2 The IP addresses or hosts are reachable. 3 SNMP is enabled on the given IP addresses or hosts.
The Nagios Core Console is not displaying the Dell EMC devices that are discovered using the Dell EMC discovery script 1 The host and service definition files exist in the /dell/config/objects folder. 2 The Nagios service has been restarted after running a discovery. 3 The host and service definition files have appropriate permissions.
3 The appropriate WSMan parameters are correctly configured in the following files: dell_resource.cfg .dell_device_comm_params.cfg Dell EMC OpenManage Plug-in specific services are displaying the message, “Component Information = UNKNOWN” NOTE: This is an expected message if the component is not available in the discovered Dell EMC device. If the component is available and you are still receiving the message, then this message is due to protocol time-out.
1 Install JAVA. 2 Navigate to /dell/install, run the command: ./install.sh java 3 Restart Nagios Core services. 4 Rediscover the Dell EMC device. The Overall Health status is not getting refreshed after receiving a Dell EMC device alert If the Overall Health service is not created for a discovered Dell EMC device, then the Dell EMC device trap will not trigger an Overall health status.
12 Frequently asked questions 1 Question: Can you provide information on Licensing of Dell EMC OpenManage Plug-in for Nagios Core?
