Product Administration › Manage Data Collector Installations

Manage Data Collector Installations

The administrator must select an IP domain and a tenant for each Data Collector installation. Each Data Collector instance can be associated with only one IP domain; the Data Collector instance that is associated with that IP domain carries out discovery requests.

IP domains are logical groupings that identify data from different devices and networks. Monitoring by domain means that IP addresses with associated interfaces or applications that belong to separate customer networks are monitored separately. When combined with appropriate permissions, IP domains are monitored from a single console, but users view data only for the domains that they monitor.

A tenant represents a customer environment that a managed service provider administers. Each tenant environment is independent and effectively functions as a separate instance of CA Performance Center. Each instance can contain multiple users and roles that are not shared among tenants.

The Default Tenant represents the tenant space for the managed service provider within the managed infrastructure. Assign the Default Tenant if you are not deploying multi-tenancy. In a single-tenant environment, the Default Tenant is the space used for monitoring the entire infrastructure.

Follow these steps:

1. Open CA Performance Center as an administrator.
2. Navigate to the Data Collectors page.
3. Select a Data Collector instance from the list.
4. Verify that Data Collector is available for assignment. The Polled Items column lists the number of polled devices and components that are assigned to this Data Collector instance.

   Important! If the number of polled devices and components is greater than one, you cannot change the tenant or IP domain assignment for the Data Collector instance.

5. Click Assign.

   The Assign Data Collector dialog opens.

6. Select the tenant that you want to assign to this Data Collector instance from the drop-down list.

   All monitored devices and components that this Data Collector instance discovers are automatically associated with this tenant.

   Select 'Default Tenant' if you want to use the default tenant.

7. Select the IP domain that you want to associate with this Data Collector instance.

   All managed devices and components that this Data Collector instance discovers are automatically associated with this IP domain.

8. Click Save.

   The tenant and IP domain are assigned to the Data Collector installation.
