Red Hat Enterprise Virtualization - Extractor service

1. Make sure that you are collecting data from the supported versions of RHEV: 4.4 (with compatibility version 4.7), 4.3, 4.2, 4.1, 4.0
2. Create an ETL user and assign the login permissions to the user. The ETL uses this user and the API calls to connect to RHEV for data collection.
   1. Log into the Red Hat Virtualization Manager terminal.
   2. Run the following command to create a new user:
      ovirt-aaa-jdbc-tool user add bmcETL --attribute=firstName=bmc_etl

1. 1. Change the password of the user by using the following command:
      ovirt-aaa-jdbc-tool user password-reset bmcETL --password=pass:<new password>

1. 1. Ensure you can log in to the RHEV console using the ETL user you created. If you are unable to log in, you might need to unblock the user using the following command:
      ovirt-aaa-jdbc-tool user unlock bmcETL
   2. Log in to the RHEV console as an admin. Navigate to Portals > Administration Portal.
   3. From the left navigation pane, go to Administration > Users section. 
   4. Click Add and search for the newly added bmcETL user from the list of users. Click Add to save the changes. 
   5. Create a role for the bmcETL user. 
      1. Navigate to Administration > Configure > Roles section.
      2. Click New. 
      3. Enter the name and the description, and from Account Type, select Admin. 
      4. In the Check boxes to Allow Action section, expand System > Configure System. Verify that only the Login Permissions are available to the bmcETL user. 
      5. Click OK to save the role. 
      6. Navigate to the System Permissions section, and click Add. 
      7. On the Add System Permission to User screen, search for the bmcETL user and select it. From the Role to Assign dropdown list, select the name of the role that you have created in step 2g (iii). 
      8. Click OK to save the preferences. 

The ovirt-aaa-jdbc-tooltool is used for managing users, groups, permissions, and other authentication and authorization aspects. When you have a Red Hat Virtualization environment up and running, the necessary components, including the ovirt-aaa-jdbc-tool, are typically installed as part of the overall deployment.

You must configure the ETL to connect to Red Hat Enterprise Virtualization 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

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 under the Last run tab. The Add ETL page displays the configuration properties. You must configure properties in the following tabs: Run configuration, Entity catalog, and RHEV Manager API Connection.
3. On the Run configuration tab, select Red Hat Enterprise Virtualization - 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 the other ETLs access the same entities that are used by this ETL.
     • From the Sharing with Entity Catalog list, select an entity catalog name that is shared between ETLs.
   • Private Entity Catalog: Select if you want to use this ETL independently.
     If you are collecting business services data, we recommend that you select Shared Entity Catalog to avoid duplication of entities.
5. Click the RHEV Manager API Connection tab, and configure the following properties:
   • The name of the host where the RHEV-M console is installed and the port number for the RHEV-M API.
   • Transport type as HTTP or HTTPS. The default is HTTPS.
   • The user name, domain the user belongs to, and the password to connect to the RHEV-M API. 

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

   The [confluence_table-plus] macro is a standalone macro and it cannot be used inline. Click on this message for details.
   This macro generates standalone content. As a consequence you need to make sure to use a syntax that separates your macro from the content before and after it so that it's on a line by itself. For example in XWiki Syntax 2.0+ this means having 2 newline characters (a.k.a line breaks) separating your macro from the content before and after it.*Scheduler compatible with this ETL: Remote ETL Engine.

7. Click Save.
8. The ETL tasks page shows the details of the newly configured Red Hat Enterprise Virtualization - Extractor Service ETL.
