System Groups

When you register a data source, system groups are automatically created to organize the items in the database. Use system groups to build custom groups and manage the items in your inventory.

System groups cannot be edited; however, you can add them to custom groups as subgroups and can assign them to user accounts as permission groups. A lock icon indicates their read-only status: System groups are read-only as indicated by the lock symbol..

The following system group is automatically included in the Groups tree:

Inventory System groups are read-only as indicated by the lock symbol.

Includes all managed items that are discovered by all registered data sources. Organizes data sources, IP domains, and managed items in subgroups.

If you have registered a CA Infrastructure Management Data Aggregator data source, the following system group appears at the same level in the Groups tree:

Collections System groups are read-only as indicated by the lock symbol.

Represents the collections of managed items. Collections are groupings of items that are monitored using the rules that are specified in CA Infrastructure Management monitoring profiles. The "factory" collections are not visible in the Groups tree.

This group lets you create custom CA Infrastructure Management collections. Any subgroup that you add to the Collections group is synchronized to the CA Infrastructure Management Data Aggregator as a collection.

Special groups for multi-tenant deployments also appear after you create at least one custom tenant. For more information, see Groups for Multi-Tenant Deployments.

The Inventory group contains its own system subgroups to organize managed items by their type. Multiple data sources share some system subgroups, such as the Routers group. Other subgroups are specific to a single data source.

The following system groups appear when you expand the Inventory node:

All Items System groups are read-only as indicated by the lock symbol.

Includes subgroups of managed items, which are categorized by type.

Data Sources System groups are read-only as indicated by the lock symbol.

Includes all data sources that are registered with CA Performance Center. Each data source has a dedicated group under this node.

Note: A data source typically has its own system subgroups, which you can see when you expand the data source group.

IP Domains The IP Domains group contains IP domains defined in the system.

Includes all of the custom IP domains created by the administrator. Also includes the Default Domain, which contains all items that are not explicitly assigned to a custom domain. For more information, see IP Domains.

The All Items subgroup of the Inventory group contains the following system subgroups of items. You can click any of these groups to view their actual membership on the Items tab:

All Pingable Devices System Groups are automatically created when items are discovered

Includes all discovered devices that cannot be contacted using SNMP.

ESX Hosts System Groups are automatically created when items are discovered

Includes all VMware servers that host virtual machines.

Interfaces System Groups are automatically created when items are discovered

Includes router and switch interfaces from all data sources.

Routers System Groups are automatically created when items are discovered

Includes all routers from all data sources.

Servers System Groups are automatically created when items are discovered

Includes all servers from all data sources.

CA Application Delivery Analysis Networks System Groups are automatically created when items are discovered

Includes all networks that CA Application Delivery Analysis has observed. A CA Application Delivery Analysis network consists of an IP address and mask.

Switches System Groups are automatically created when items are discovered

Includes switches from all data sources.

Virtual Machines System Groups are automatically created when items are discovered

Includes all virtual machines running on all ESX servers.
