116 Configuring Dell OpenManage IT Assistant to Monitor Your Systems
Tom may monitor systems based on subnet range, host name, or IP address.
Although it is advisable to limit the number of community names used in
a network, Tom may also define multiple read-only and read-write
community names in his network environment. For example, Tom may
decide that he wants a common Get community name for all systems on
this network but unique Set community names for certain data centers.
NOTE: IT Assistant offers a troubleshooting tool that can be useful in analyzing
problems with discovery and inventory. Access the tool by selecting Tools

Troubleshooting Tool from the menu bar, or by right-clicking a device in the Device
view and selecting Troubleshoot. For more information, open the Troubleshooting
Tool dialog box and click Help.
Configuring SNMP on Each Managed System
Before configuring discovery, Tom needs to determine the Get and Set
community names he wants to use for his network, and install and configure
the SNMP agent and operating system SNMP service of each server he wants
to manage.
Table 6-2 provides information about the remote systems that Tom is
monitoring.
