(NNMi Advanced - Global Network Management feature) As administrator of the Regional Manager, you can specify which Node object data Global Managers can access:
Prerequisites:
-
Each NNMi management server must have a static, routable IP address as the Management Address (for all SNMP/ICMP communication). See Configure default SNMP, management address, and ICMP settings and Specific Node Settings Form (Communication Settings).
- Verify that your Tenant definitions have unique names across the entire Global Manager's domain: Tenant Best Practices for Global Network Management.
-
All NNMi management servers in your network environment that participate in Global Network Management (Global Managers and Regional Managers) or Single Sign-On (SSO) must have their internal time clocks synchronized in universal time.
Caution Use a Time Synchronization program, for example, the Linux tool Network Time Protocol Daemon (NTPD) or one of the available Windows operating system tools.
To provide all Node object data to Global Managers in your environment:
- Do nothing. NNMi automatically forwards all Node object data unless a Forwarding Filter is defined. Also see, About Multi-Tenancy and Global Network Management.

(NNMi Advanced - Global Network Management feature) The Global Manager and the Regional Manager maintain separate sets of data. Conclusions about each Node are derived from the available data and can sometimes be different. Regional Managers forward the results of each Auto-Discovery cycle to the Global Manager. The Regional Manager can have a Node Group filter configured to limit the amount of data that is forwarded to the Global Manager. Filters are usually unnecessary for Global Network Management. Do not filter out nodes that are important for connectivity in your network environment to ensure NNMi has the data needed for accurate root cause analysis.
-
Navigate to the Global Network Management form:
- From the workspace navigation panel, select the Configuration workspace.
- Select the Global Network Management form.
- Select the Forwarding Filter tab.
-
Click the Node Group
Lookup icon and select one of the options from the drop-down menu:-
Show Analysis to view Analysis Pane information for the currently selected Node Group name.
-
Quick Find to view and select from the list of all existing Node Groups. -
Open to display the details of the currently configured (selected) Node Group (see Node Group form for more information). -
New to create a new Node Group (see Create Node Groups for more information).
-
- Click
Save and Close. -
Global Managers in your network environment can now access only information about the Nodes in the specified Node Group. If any Global Managers have previously gathered a wider range of Node object data, that extra data is automatically removed from the Global Managers database.
To verify that your Forwarding Filter is working as expected, wait until the next NNMi rediscovery cycle finishes on your NNMi management server and then log on to the Global Manager. Follow the directions in View the NNMi Management Servers' Domain List. You should see only the members of the Node Group specified as your Forwarding Filter.
Incidents associated with the specified Nodes are not forwarded to the Global Manager. Each server maintains an independent group of incidents.
Regional Manager administrators can make exceptions to this for SNMP traps. The administrator must specifically configure forwarding to the Global Managers:
