BMC Discovery 11.x Extractor

Use the BMC Discovery ETL to fetch the relationships between business services, applications, and the supporting IT infrastructure. The ETL connects to the BMC Discovery to collect this mapping information. You can use it to effectively manage your business services and applications. These relationship details are displayed as a hierarchy in the BMC Helix Continuous Optimization. The ETL makes the REST API calls for fetching the mapping information from BMC Discovery.

Supported BMC Discovery versions:

  • 21.02
  • 20.02, 20.08
  • 11.3, 11.2, 11.1

The following video (5:49) provides information about the enhancements done in the BMC Discovery 11.x extractor.

      1. Log in to the BMC Discovery as an administrator.
      2. Click Manage > Credentials.
      3. Click Add > Other, and select vCenter from the Credentials Types list.

      4. Specify the vCenter credentials and other details, and click Apply.
      5. Run the discovery process.

Step II. Configure the ETL

You must configure the ETL to connect to BMC Discovery for data collection. ETL configuration includes specifying the 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.

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 BMC Discovery Extractor

  3. On the Run Configuration tab, select BMC Discovery 11.x Extractor 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 BMC Discovery 11.x 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 BMC Discovery.
  5. Click the BMC Discovery Extractor tab, and configure the following properties:

    PropertySpecify
    Data Integration API URLThe data integration API URL through which the REST API calls are initiated.
    UsernameThe name of the user that you created during the preconfiguration steps.
    PasswordThe password of the user.
    Business Service hierarchy

    To create a business service hierarchy, retain the default selection, and specify the appropriate manual group name. The default name is Service. The business service hierarchy is created based on the manual group value. The following scenarios explain when business services are created.

    You have added a manual group called Service to the business application instances in the BMC Discovery as follows:

    Manual group additionsResult of running the ETL
    • BAI_AIX (Service = DB)
      • BAI_2 (Service = HR)
    The business service called "DB" is created only for the topmost BAI_AIX application instance. It is not created for the child application instance.

    • BAI_AIX (no manual group added)
      • BAI_2 (Service = HR)
    Business service is not created.

    You have added the manual group called Service to the business application instance and the associated virtual machines in the BMC Discovery as follows:

    Manual group additionsResult of running the ETL
    • BAI_AIX (no manual group added)
      • virtual_machine_1 (Service = HR)
    Business service is not created.
    • BAI_AIX (Service = DB)
      • virtual_machine_1 (Service = HR)
    Business service called "DB" is created only for the BAI_AIX application instance. It is not created for the virtual machine.


    You have added a manual group called Service for the virtual machines of unassociated hosts. After you run the ETL, business services are created only for the virtual machines for which the Service manual group is added.

    Import Manual Groups as TagsSpecify the manual groups that you want to import as tags for the business application instances. The default manual groups are AppTier and Owner. You can use these tags for creating service pools.
    Use proxy

    Specify whether you want to use a proxy server, and provide the following details. The default selection is No.

    • The fully qualified domain name and the port number of the proxy server host.
    • If the proxy server requires authentication, select Yes, and specify the proxy server user name and password.

    By default, the proxy server uses the HTTPS protocol for communication.

  6. (Optional) Override the default values of properties in the following tabs:
