BMC - Atrium CMDB extractor

Before you configure and run the ETL, ensure that the following preconfiguration tasks are completed:

• The specific version of Atrium CMDB is installed and it is running.
• The BMC Remedy AR system server is registered with a portmapper and the port 111 firewall does not block the portmapper port.
• The configured Atrium user must have administrative privileges on the BMC Atrium server. These privileges are required that BMC Atrium can be scanned to fetch information about computer systems, hardware configuration, and business service instances.

You must configure the ETL to connect to Atrium CMDB 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 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 CMDB connection parameters.
3. On the Run configuration tab, complete these steps:
   1. From the ETL module list, select BMC - Atrium CMDB Extractor. The name of the ETL is displayed in the ETL task name field. You can edit this field to customize the name.
   2. Specify the datasets that you want to add to the ETL configuration. The ETL collects data of metrics that are associated with these datasets.

      1. Click Edit
      2. Select one (click) or more (shift+click) datasets from the Available datasets list and click >> to move them to the Selected datasets list.
      3. Click Apply.
         The ETL collects data of metrics associated with the datasets that are available in the Selected datasets list.
         
2.  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.

3. Click the CMDB connection parameters tab, and configure the following properties:

4. (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.
   
   

5. Click Save.

   The ETL task page shows the details of the newly configured BMC - Atrium CMDB ETL.

(Optional) B. Configuring the advanced properties

You can configure the advanced properties to change the way the ETL works or to collect additional metrics.

To configure the advanced properties:

1. On the Add ETL page, click Advanced.

2. Configure the following properties:
   

   Run configuration

   Property	Description
   Run configuration name	Specify the name that you want to assign to this ETL task configuration. The default configuration name is displayed. You can use this name to differentiate between the run configuration settings of ETL tasks.
   Deploy status	Select the deploy status for the ETL task. For example, you can initially select Test and change it to Production after verifying that the ETL run results are as expected.
   Description	A short description of the ETL module.
   Log level	Specify the level of details that you want to include in the ETL log file. Select one of the following options: 1 - Light: Select to add the bare minimum activity logs to the log file. 5 - Medium: Select to add the medium-detailed activity logs to the log file. 10 - Verbose: Select to add detailed activity logs to the log file. Use log level 5 as a general practice. You can select log level 10 for debugging and troubleshooting purposes.

   CMDB connection parameters

   
   

   Property	Description
   TCP Port	Specify the TCP port number that is used by BMC Atrium. The Atrium administrator can provide this port number. You need to specify this port number only if the BMC Remedy AR system server is not registered with a portmapper or if a Port 111 firewall blocks the portmapper port. Otherwise, you do not need to specify the port number because the portmapper automatically locates the port.
   Use UUID for VMware vms	Specify if the UUID must be used instead of the VM name to identify VMware guest machines.
   Import VMware Data	Import VMware host and guest machines.
   Import Application Data	Select True if you want to view the application-wise relationship in the hierarchy.
   List additional cmdb relationship classes	Specify the relationship classes that you want to use for displaying CMDB relationships. By default, the following relationship classes are supported: BMC_Dependency BMC_Impact BMC_Component
   Enable Diagnostic Log	Select True if you want to troubleshoot issues related to CMDB and understand which Configuration Items (CI) and relationships are fetched and how they are associated. Enabling this option will generate a diagnostic log file in zipped format. This file will be available in the downloaded logs.

   Import filter

   Configure one or more filtering properties in this section to include or exclude entities while importing.

   Property	Description
   Whitelist file path	Use this property to import only specific business services or computer systems. By default, the ETL imports all business services and computer systems. To include business services or computer systems In a text file, add the names of business services or computer systems that you want to import in the following format: ClassName;AttributeName;AttributeValue In the Use file at path field, specify the path to this text file. Run the ETL and verify that only the specified business services or computer systems are imported in the hierarchy. Example: To import business services BService_1 and BService_2 and their computer systems, add them to the text file as follows: BMC_BUSINESSSERVICE;Name;BService_1 BMC_BUSINESSSERVICE;Name;BService_2 After you run the ETL, only BService_1 and BService_2 business services and their computer systems will be displayed in the hierarchy. For information about CMDB class and attribute names, see Common Data Model advanced concepts.
   Blacklist file path	Use this property to exclude specific business services or computer systems while importing. By default, the ETL imports all business services and computer systems. To exclude business services or computer systems In a text file, add the names of business services or computer systems that you want to exclude while importing in the following format: ClassName;AttributeName;AttributeValue In the Use file at path field, specify the path to this text file. Run the ETL and verify that the specified business services or computer systems are not displayed in the hierarchy. Example: To exclude computer systems hp1appo1 and hp1app02 while importing, add them to the text file as follows: BMC_COMPUTERSYSTEM;Name;hp1appo1 BMC_COMPUTERSYSTEM;Name;hp1app02 After you run the ETL, these computer systems will not be imported and displayed in the hierarchy. For information about CMDB class and attribute names, see Common Data Model advanced concepts.
