IP Domains

IP domains separate monitored devices from different networks to resolve IP address conflicts. For example, you monitor two networks and each network includes a separate device with the same IP address.

IP domains separate monitored devices from different networks to resolve IP address conflicts. For example, you monitor two networks and each network includes a separate device with the same IP address.
As a service provider, use IP domains to monitor multiple discrete networks that belong to different customers. Each customer, or tenant, contains one or more IP domains. The Data Collectors associate managed items and data with the assigned IP domain. Customer user accounts see only the relevant IP domains. Service provider administrators see the data from all IP domains.
Administrators and Designers can create custom dashboards to monitor activity on a specific domain or group of domains.
To view IP domains, go to

IP Domains and Other Data Sources
CA Network Flow Analysis
,
CA Application Delivery Analysis
, and CA Unified Communications Monitor include support for IP domains. To apply domains to the data sources, register the data source with
CA Performance Center
. When you create IP domains in
CA Performance Center
, the domain identifiers become visible in the registered data sources after synchronization.
The following managed item types can be associated with an IP domain:
  • Devices
  • Interfaces and interface addresses
  • Networks
  • VoIP Locations
Data sources report a domain identifier that associates monitored items with a specific IP domain. Items that are not assigned to a custom domain in the data source are associated with the Default Domain.
CA Spectrum
uses IP domains to determine which models are synchronized to
CA Performance Management
.
Add or Edit an IP Domain
IP domains are required for monitoring multiple tenants or environments with overlapping IP addresses. Create custom IP domains so the data sources can associate monitored items with specific domains and tenants.
The Default Domain is automatically created. This domain includes any items that are not assigned to a custom domain in the data source.
The procedure requires the Administer IP Domains role right.
Follow these steps:
  1. Select
    Administration
    ,
    IP Domains
    .
  2. Click
    New
    .
  3. Specify a name and description.
  4. (Optional) Configure a device name alias or interface description override. Click
    Browse
    , select the file, and click
    Open
    .
    Use a CSV or TXT file with the following format:
    IP_Address,name,description,alias/alternate_description
    Use the primary IP address of the associated devices. To find the primary IP address, look at the Address column of the Inventory Devices list.
    You
    can
    use the same alternate interface descriptions for more than one interface.
    Example:
    172.24.36.107,ethernet_7,vmxnet3 Ethernet Adapter,Connection to Dallas
    To change or remove an alternate description or device name alias, import a new file. To remove the alias or alternate description, leave the final column blank. When you remove the alias or alternate description, the original name or description reappears.
    If you use a spreadsheet program to remove all the alternate aliases or descriptions from the file, include a column heading for that column.
    Updates to device name aliases and interface descriptions can take up to 5 minutes to appear.
    The preferred method to apply device name aliases and alternate interface descriptions is through REST. For more information, see Set the Alias Name for a Device and Set Interface Name Aliases.
    To update multiple device aliases, use the script. For more information, see Set Alias Names For Multiple Monitored Devices.
  5. (Optional) To assign a primary and secondary DNS address for the domain in
    CA Network Flow Analysis
    , select
    DNS Settings
    , and specify the required values.
    Only
    CA Network Flow Analysis
    uses the DNS settings.
    CA Performance Management
    does not directly use the DNS settings.
  6. Click
    Save
    .
    The IP domain appears in the list immediately, and the changes apply to the data sources in the next synchronization. If you edit an IP domain, historical data for monitored items remains unchanged.
Assign Items to an IP Domain
To add items to an IP domain, associate a Data Collector with the IP domain and create a discovery profile that uses the IP domain. Each Data Collector associates managed items with a single IP domain. To enable multi-tenant deployments, assign an IP domain to each Data Collector. Before you install a Data Collector, create the tenants and IP domains that you require.
You can associate multiple Data Collectors with a single IP domain.
You cannot move items from one IP domain to another.
To assign items from other data sources to an IP Domain, see the documentation for that data source or see the following pages:
In
CA Spectrum
, use IP domains to determine which models are synchronized with
CA Performance Management
. For more information, see the sp documentation.
This procedure requires the Administer Data Sources role right, and the Administrator product privilege for the Data Aggregator data source.
Follow these steps:
  1. Select
    Administration
    , and click the Data Aggregator data source.
  2. Expand
    System Status
    , and click
    Data Collectors
    .
  3. Select an IP domain and a tenant for each Data Collector in the list, and click
    Assign
    .
    You cannot assign a Data Collector that is monitoring devices other than itself to a different IP domain.
  4. Create a Discovery profile that is associated with the IP domain and run discovery.
    For more information, see Discovery.
Delete an IP Domain
When you delete an IP domain, all monitored items in that IP domain are deleted, including historical data. The items are also deleted from registered data sources that use IP domains, such as
CA Network Flow Analysis
,
CA Application Delivery Analysis
, and CA Unified Communications Monitor.
CA Spectrum
devices in the IP domain are removed from
CA Performance Management
, but
CA Spectrum
continues to monitor the devices.
When you delete an IP domain, associated Data Collectors and discovery profiles become inactive. Assign another IP domain to continue polling or discovery.
If you want to retain any associated data, do not delete an IP domain. You cannot recover deleted data.
