118 Configuring Dell OpenManage IT Assistant to Monitor Your Systems
NOTE: Ensure that you have a separate range for Dell|EMC devices. This is
because apart from the SNMP credentials, Dell|EMC devices also require
the Navisphere credentials.
Tom clicks Next to go to the next step.
NOTE: The Import Node List utility offers a convenient way to specify a list of
host names, IP addresses, and subnet ranges for IT Assistant to discover.
See the IT Assistant Online Help for instructions on how to run the utility from
the command line. The importnodelist.exe file is in the /bin directory.
4 In step 2 of the wizard, Tom enters the Internet Control Message Protocol
(ICMP) time-out and retry values for the range. Tom chooses the highest
time-out retry value for the ranges that he combines. For example, in
Table 6-2 for Data Center Servers 3 to Data Center Servers 9, Tom chooses
148 milliseconds, the highest time-out interval in that range.
5 In step 3 of the wizard, Tom configures the SNMP parameters to be used
during discovery:
• Tom ensures the
Enable SNMP Discovery option is selected.
NOTE: Tom will have to select this option if he wants to discover the Virtual
Machines on his network.
• Tom enters a case-sensitive value for the Get Community name.
The
Get Community name is a read-only password that SNMP agents
installed on managed systems use for authentication.
Tom’s considerations:
Tom considers the following as he selects a
Get Community name:
Each SNMP managed system has a
Get Community name. Tom
ensures that he lists each of the community names on all of the
systems he wants to manage. If Tom’s managed systems have more
than one community name, he can enter multiple community names
separated by commas in the
Get Community name field.
Although the
Get Community name affects read-only information
retrieved by IT Assistant from managed systems, such as the results of
discovery, status polling, and alert logs, Tom wants to limit access to
this data. Therefore, he changes the default
Get Community name
(
public ) to a name known only to him and his system administrators.
