E-mail Alert Action
Question: Why am I not receiving e-mails after setting up e-mail alert action?
Answer: If you have an Antivirus Client installed on the system, then congure it to allow e-mails.
Discovery
Question: Why are SUSE Linux Enterprise and Red Hat Enterprise Linux based-servers not displayed in the Server category after I
have discovered it using SSH protocol?
Answer: The OpenManage Essentials SSH plugin uses sshlib2. sshlib2 fails to authenticate Linux servers which have disabled the
Authentication by password option. To enable the option:
1. Open the le /etc/ssh/sshd_cong in edit mode and search for the key PasswordAuthentication.
2. Set the value to yes, and save the le.
3. Restart the sshd service /etc/init.d/sshd restart.
The servers are now displayed under the Server category in the Device tree.
Question: What troubleshooting can I do if a discovery task fails to create or run?
Answer: Ensure that the DSM Essentials Task Manager service is running in Windows services.
Question: Why are my ESX virtual machines not correlated with their ESX host server?
Answer: You must discover the ESXi host server using SNMP and WSMan or the guest virtual machine will not correlate correctly
when discovered using SNMP.
Question: Why are devices discovered with WMI getting classied as Unknown?
Answer: WMI discovery classies a device as unknown when the credential for a user account in the Administrators group (not
Administrator) is supplied for the discovery range in some cases.
If you are seeing this issue, read the KB article at support.microsoft.com/?scid=kb;en-us;951016 and apply the registry work as
described. This resolution applies to managed nodes with Windows Server 2008 R2.
Question: Why are Dell devices discovered using WS-Man with root CA certicate getting classied as Unknown?
Answer: There may be a problem with the root certicate you are using to discover the WS-Man target(s). For instructions to
discover and inventory WS-Man target(s) using a root CA certicate, see Discovering and Inventorying Dell Devices Using WS-Man
Protocol With a Root Certicate.
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 nd if someone is probing a system, although its better nowadays to just sni packets and nd out the
community name.
If you use multiple community names on the network, and some management might overlap, users may want to turn these o 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?
