The Configuration Change Report includes a Filter that you can alter at runtime. By default, the
report filters on Type only. If you want more filter criteria—like device IP, and/or date ranges—you
must edit the Report filter. To edit the filter, in the Reports manager, right click the Configuration
Change Report, and select Open, then edit the filter in the Filter screen by selecting that node on
the left.
Tip
A recommended best practice is to execute the CD process as an operation run against multiple
resources following a scheduled group backup of these resources. If you run backups every day, the
Configuration Change Report
then shows the daily changes, until they are purged from the database.
The application stores the specifics of what changed for future reporting.
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.
Check your vendor’s manuals to determine how to forward configuration change information
to Dell OpenManage Network Manager for your system.
2
When Dell OpenManage Network Manager receives a configuration change notification, the
device transmits an event 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.
5
Once this occurs, the Change Determination label moves to point to the same configuration
which is reflected by the Current label.
