Troubleshooting

This section lists the problems that you may encounter while using the Dell OpenManage Plug-in for

Nagios XI and their workarounds.

All the services (service parameters) for the devices

discovered using SNMP are not getting displayed in the

Nagios XI console

1. Ensure that you have installed Net-SNMP version 6.0.1 or later.

2. Rediscover the devices.

Status Information gets truncated at 256 characters in

the Service Detail view

In the Nagios XI interface, the Status Information shown for a service stops at 256 characters (anything

after is truncated).

Unable to connect to iDRAC

If you cannot connect to iDRAC, this could be due to iDRAC7 or iDRAC8 being enabled by default with

Transport Layer Security (TLS) versions 1.1 or higher as the cryptographic protocol for secure

connections. For more information about resolving this problem, see bugzilla.redhat.com/show_bug.cgi?

IPv6 SNMP traps are not getting associated with the

corresponding Dell Devices

This is not due to a limitation of the Dell OpenManage Plug-in but due to a bug in how the Net-SNMP

libraries spool the received IPv6 traps. Due to this, SNMPTT is not able to resolve the IPv6 address to the

correct DNS record and this consequently results in an incorrect IPv6 address submitted to Nagios XI.

For more information about the Net-SNMP bug, see sourceforge.net/p/net-snmp/bugs/2704/.
