Event/Trap-Based Change Determination
The following steps to trigger Change Determination based on events received by OpenManage
Network Manager. Your devices must transmit traps to the OpenManage Network Manager
installation, and must emit traps when changes occur, or this does not work.
1 Back up the configuration file for a device you have discovered.
2 Make a change to that device with the Managed Resources editor, or from a Direct Access
command line.
3 Such changes make the device emit an event that may have further consequences. For
example, for Juniper devices, the Juniper JUNOS Configuration Changed event is a
correlation event.
4 To provide a response (and to normalize the emitted event), create an automation rule that
emits a
redcellEquipmentConfigChangeNotification event when OpenManage
Network Manager receives creates a event in response to events like the
jnxCmCfgChange
event that occurs when Juniper devices change.
5 Create a rule to respond to redcellEquipmentConfigChangeNotification by
running the Change Determination process. You do not have to back up the configuration
after the change. See How to:
Create Event Processing Rules to Trigger Change
Determination Process
below.
6 To see the change itself, run the Change Determination Report (see Compliance and
Change Reporting
on page 524 and How to: Report on Change Determination on page
525). The report displays the changes made.
How To:
Create Event Processing Rules to Trigger Change Determination Process
This exercise creates an Event Processing rule that has Change Determination respond to an event.
The steps to configure such an event processing rule are as follows:
1 Create a new event processing rule by right-clicking in Event Processing Rules > New > Post
Processing
rule in the Event Processing Rule portlet.
2 Enter the name in the field labeled Name. (Example: Update Config Change Flag)
3 Click Next to go to the Filter tab.
4 For the Specify Events panel, click on the Add button to select the event to which this rule
responds. A selector listing available events appears.
NOTE:
Notice you can limit the selector’s displayed events by entering text in the filter at the top of the selector
screen.
5 In the selector, click the event definition (here:
redcellEquipmentConfigChangeNotification ), and confirm your selection.
6 Click Done to accept the Event(s) you have configured.
7 Notice you can further filter which events this rule responds to with the lowest panel in this
screen’s
Filter Conditions panel by clicking Add Filter. For example, you could create a rule
that responds only to events from a particular IP address. For now, we will not configure
additional filters.
8 Click Next to open the Actions tab.
