Configuring Dell OpenManage IT Assistant to Monitor Your Systems 85
Both Jane and Tom must configure the Simple Network Management
Protocol (SNMP) systems management protocol to discover their systems
and to receive traps (asynchronous, alert notifications) that report the status
of their components. On managed systems, the Server Administrator agent
generates SNMP traps in response to changes in the status of sensors and
other monitored parameters on a managed system. In order to correctly send
these traps, the operating system’s SNMP service must be configured with
one or more trap destinations that correspond to the system where
IT Assistant is installed.
Details on Configuring the SNMP Service
For detailed information about SNMP configuration for the IT Assistant
system and for all supported managed system, operating systems, see
"Configuring the SNMP Service."
Configuring SNMP on Systems You Want to Manage
In addition to having the SNMP service installed and running on the
IT Assistant system, each managed system’s operating system must have
the SNMP service or daemon configured.
SNMP Best Practices
When configuring SNMP, adhere to the following requirements:
• Use a host name or a static IP address for the IT Assistant system.
• On all managed systems, configure the static IP address or host name
as the SNMP trap destination. If you use a host name as the SNMP trap
destination (the IT Assistant system name), you must correctly configure
name resolution on your network.
• Ensure that
Get and Set community names for SNMP are different.
• When assigning community names to managed systems, keep the total
number of different community names low. The fewer community names,
the easier it will be to manage your network.
