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).
For more information to resolve this problem, see support.nagios.com/kb/article.php?id=478 or Common Problems Articles
in support.nagios.com/kb.
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?id=1170339.
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/.
For more information about how to configure Nagios XI to receive IPv6 traps, see Nagios Knowledge Base (KB) article at
support.nagios.com/kb/article.php?id=499.
The Nagios XI Console is not displaying the trap service for
the discovered Dell devices
1. Install SNMPTT.
If SNMPTT is not installed, then the trap service is not created for any of the discovered Dell device.
