How To:
Report on Change Determination
Follow these steps to produce regular change determination reports:
1 First, insure the devices you want to scan are discovered, and send change notifications to the
application server.
Juniper JUNOS-based routers, for one example, provide configuration change information
with an SNMP trap. The following configuration determines that configuration change traps
are being sent to a host 192.168.1.24:
trap-group test {
categories {
configuration;
}
targets {
192.168.1.24;
}
}
Check your vendor’s manuals to determine how to forward configuration change information
to OpenManage Network Manager for your system. See
Forwarding Configuration Change
Commands
on page 526 for others.
2 When OpenManage Network Manager receives a configuration change notification, in the
JUNOS-based example, the device transmits an event (jnxCmCfgChange) to the
OpenManage Network Manager mediation server. When received, this event automatically
generates an event called OpenManage Network
ManagerEquipmentConfigChangeNotification. Event history displays that notification.
3 When OpenManage Network Manager receives the OpenManage Network
ManagerEquipmentConfigChangeNotification event, it can initiate (if enabled) an event
processing rule called
Configuration Change .
This processing rule triggers a flag in the OpenManage Network Manager database saying a
change has occurred in the device’s configuration and that OpenManage Network Manager
should run change determination against the device when requested.
4 When you run OpenManage Network Manager’s change determination process, it reviews the
flag setting in the database and backs up a managed device if the flag indicates a change. This
backup updates the OpenManage Network Manager system label
Current which is then
compared to the OpenManage Network Manager system
Change Determination label.
OpenManage Network Manager then writes the differences between the two labelled
configurations to its database, where it is available for reporting purposes.
