Add an IP Domain

Synchronize a Data Source

Edit an IP Domain

You can edit the custom IP domains that you have created. The changes are propagated to all registered data sources at the next synchronization.

The Default Domain cannot be edited. It must remain sufficiently generic to include all managed items that are not assigned to a custom domain by the data sources.

When you have finished editing domain definitions, you can force a synchronization to push the changes to the data sources. Otherwise, synchronization automatically occurs approximately every 5 minutes.

Follow these steps:

1. Log in as a user with the required administrative role rights.
2. Navigate to the Manage IP Domains page.

   The page displays the current list of IP domains.

3. Click Edit.

   The IP Domains Administration dialog opens.

4. Modify the parameters as needed.
5. Click Save.

   Your changes to the IP domain are saved and are reflected in the IP Domain List.

   Changes to IP domains are not applied to managed items until synchronization has occurred. Within each tenant, managed items already reported remain unchanged in historical data views.

Delete an IP Domain

Like the associations between performance statistics and managed items, IP domain associations are stored along with items in the database on each data source console. As a result, domains cannot simply be deleted from CA Performance Center.

If you delete a domain, it can be marked as inactive in the data source. An inactive domain is not exposed in views that display new data. But if you unregister (remove) the data source and register it again later, the data source sends the domain information back up to CA Performance Center at the first synchronization. Managed items in the data source database retain the domain association.

For some data sources, deleting a domain causes data loss, such as polled device information and history. Reinstallation steps are required in such cases. Proceed with caution when you want to delete an IP domain.

In most cases, the workflow outlined in the following procedure is recommended:

Follow these steps:

1. Log in as a user with the required administrative role rights.
2. Navigate to the Manage IP Domains page.

   The page displays the current list of IP domains.

3. Select the IP domain that you want to delete.
4. Click Delete, and click Yes to confirm the deletion.

   The domain is deleted from the list of IP domains.

5. Edit the data collector for each affected data source to change the domain assignment it is using, replacing the deleted domain.

   Note: We recommend selecting another custom domain for the affected data collectors. Otherwise, they will associate items with the Default Domain.

   Any data that was previously collected and associated with the deleted domain remains associated with it and is displayed as such in historical views.
