Question: What are SNMP authentication traps?
Answer: An authentication trap is sent when an SNMP agent is hit with an enquiry that contains a
community name it does not recognize. The community names are case-sensitive.
The traps are useful to find if someone is probing a system, although its better nowadays to just sniff
packets and find out the community name.
If you use multiple community names on the network, and some management might overlap, users may
want to turn these off as they become false positives (annoyances).
For more information, see technet.microsoft.com/en-us/library/cc959663.aspx.
When an SNMP agent receives a request that does not contain a valid community name or the host that
is sending the message is not on the list of acceptable hosts, the agent can send an authentication trap
message to one or more trap destinations (management systems). The trap message indicates that the
SNMP request failed authentication. This is a default setting.
Question: Why does OpenManage Essentials not support entering host names with underscore in the
discovery wizard?
Answer: Per RFC 952, underscores are not valid in DNS names. A name (net, host, gateway, or domain
name) is a text string up to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus sign (-), and
period (.). Periods are only allowed when they serve to delimit components of domain style names.
For more information see,ietf.org/rfc/rfc952.txt and zytrax.com/books/dns/apa/names.html .
Question: What is On-demand?
Answer: On-demand is an operation where a managed system is checked for status/health by
OpenManage Essentials when an SNMP trap is received. There are no settings to be changed to enable
the on-demand feature. However, the IP address of the management system must be available in the trap
destination of SNMP service. An SNMP trap is received from the managed system when there is an issue
or failure of a server component. These traps can be viewed under the alert logs.
Question: I am unable to see alerts from an EqualLogic member under the EqualLogic server. How
should I discover the EqualLogic storage array?
Answer: EqualLogic arrays must be discovered using the SNMP version 2 protocol. In the OpenManage
Essentials Discovery Range Configuration wizard, select SNMP Configuration and provide an
appropriate community string. You must also include the IP addresses of the EqualLogic group and all
members in the discovery range.
Inventory
Question: What troubleshooting can I do if an inventory task fails to create or run?
Answer: Ensure that DSM Essentials Task Manager service is running in Windows services.
