OpenStack - OpenStack API Extractor Service

• Ensure that the following ports are open for the OpenStack - OpenStack API Extractor Service:
  • Identity Service URL (default: 35357)
  • Compute Service URL (default: 8774)
• Ensure that the user that is used to access the Identity Service is authenticated and has an admin or ro_admin (read-only admin) role assigned for the specified tenant. This user must have read access to all OpenStack resources and endpoints.

You must configure the ETL to connect to OpenStack for data collection. ETL configuration includes basic and optional advanced properties. While configuring the basic properties is sufficient, you can optionally configure the advanced properties for additional customization.

A. Configuring the basic properties

Some of the basic properties display default values. You can modify these values if required.

To configure the basic properties:

1. Navigate to Administration > ETL & System Tasks, and select ETL tasks.
2. On the ETL tasks page, click Add > Add ETL. The Add ETL page displays the configuration properties. You must configure properties in the following tabs: Run configuration, Entity catalog, and OpenStack configuration.
3. On the Run configuration tab, select OpenStack - OpenStack API Extractor Service from the ETL module list. The name of the ETL is displayed in the ETL Task name field. You can edit this field to customize the name.
   
4. Click the Entity catalog tab, and select one of the following options:
   • Shared Entity Catalog: Select if other ETLs access the same entities that are used by the OpenStack API ETL.
     • From the Sharing with Entity Catalog list, select the entity catalog name that is shared between ETLs.
   • Private Entity Catalog: Select if this is the only ETL that extracts data from the OpenStack resources.
     If you are collecting business services data, we recommend that you select Shared Entity Catalog to avoid duplication of entities.

5. Click the OpenStack configuration tab, and configure the following properties:

   Property	Description
   Identity service URL	Specify the URL for the OpenStack Identity Service. The Identity Service is used to obtain tokens for accessing cloud services. The URL is available on the Keystone server in the OS_AUTH_URL variable of the stack.sh file. If the identity service has an HTTPS URL, then the ETL communicates securely over HTTPS.
   Username	Specify the user name to access the Identity Service. Note: The name of the role that is assigned to the user must be admin or ro-admin. If you create an equivalent role with a different name, the ETL fails.
   Password required	Select this option if a password is required to access the service.
   Password	If a password is required to access the Identity Service, enter the password.
   Tenant name	Type the name of the Keystone tenant.
   Cloud name	(Optional) Type a name. If you do not enter a name, a default name is created using "Cloud_" as a prefix and the OpenStack identity endpoint (host name, IP address) as the suffix.
   Domain name	Specify the OpenStack domains from which you want the ETL to collect data. To specify domains, select Custom, and type the required domain names.
   KVMHypervisor	Enable the collection of one of the following KVM hypervisor metrics: Utilization metrics by using the agent installed on a KVM host or other data source. This is the default selection. Metrics that are available from the Nova API calls
