As a tenant administrator, perform the following steps to configure a connection with ServiceNow, verify the connection, and view the collected topology data in various BMC products.

Supported versions

This connector supports the following versions of ServiceNow for data collection:

• Quebec
• Rome
• San Diego
• Tokyo (Applicable for version 22.4.01 and later)

Before you begin

Before you configure a connection with ServiceNow , ensure that the following prerequisites are met.

ServiceNow prerequisites

• You have read permissions for the following REST API endpoints in ServiceNow:
  
  • /api/now/table/cmdb_rel_ci
  • /api/now/table/cmdb_rel_type
  • /api/now/cimodel/cmdb_ci/fullclasshierarchy
  • /api/now/table/[type], where type is determined by querying fullclassheirarchy

  • /api/now/cmdb/instance/cmdb_ci
    For information about APIs, see the ServiceNow documentation.

• You have permissions to access the ServiceNow UI.

• You have been assigned the ITIL role. For information about the ServiceNow roles, see the Base system roles in the ServiceNow documentation.

BMC Helix Intelligent Integrations prerequisites

You have the latest Technology Knowledge Update (TKU) required to collect the topology data from ServiceNow. To obtain the latest TKU, contact BMC Customer Support.

To configure a connection with ServiceNow

1. In BMC Helix Intelligent Integrations, on the CONNECTORS tab, click in the SOURCES panel.

2. Click the 

   ServiceNow

    tile.

3. Specify the following source connection details:

   1. Specify a unique instance name.

      Recommendation

      We recommend that you specify the instance name in the following format: 

      <sourceType>_<sourceControllerServerName>{_<InstanceQualifier>}                                      

      The instance qualifier helps you to distinguish the multiple instances configured from the same source server. For example, you can name your instances as, SN_Host_PROD, SN_Host_TEST, and so on.

   2. Specify the ServiceNow host name and port number (default value is 443).
   3. Specify the ServiceNow HTTP or HTTPS port number depending on the connection protocol. The default port number is 8089.
   4. Select the HTTPS check box if you plan to use an https connection to the ServiceNow host.
   5. Specify the user name and password for the ServiceNow instance. Ensure that the specified user can access the ServiceNow   REST API.
4. Click VALIDATE AND CREATE.
   The specified connection details are validated and the corresponding source connection is created in the Source Connection list.

5. Select the source connection that you created from the list if it is not selected already.

   Important

   The destination host connection is created and configured automatically when you create a connection for a source. 

6. Click the topology data type and specify the configuration parameters in the Collectors section as described in the following table:
7. Click CREATE COLLECTORS  to create the required collector streams for the topology data type.
8. Click the topology data type and specify the configuration parameters in the Distributors section as described in the following table:
    
9. Click CREATE DISTRIBUTORS to create the required distributor streams for the topology data type.
10. Click one of the following buttons:
    • SAVE STREAM: Click this button if you want to edit the integration details before creating the instance. After you save the stream, the instance that you created is listed in the SOURCES panel. Move the slider to the right to start the topology data stream.
    • SAVE AND START STREAM: Click this button if you want to save the integration details and start receiving topology data immediately.

          For more information about data streams, see Starting-or-stopping-data-streams.

To verify the connection

In BMC Helix Intelligent Integrations , on the SOURCES panel, confirm that the topology data stream for the integration you created is running. Data streaming is indicated by moving colored arrows.

A moving light blue arrow () indicates that topology data is being streamed.

To view data in BMC Helix applications

View data collected from ServiceNow in multiple BMC Helix applications.

To view topology in BMC Helix Discovery

1. In BMC Helix Discovery, select Explore > Data.

2. Click the folder link corresponding to the entity for which you have collected data from ServiceNow. 
   For example, if you have collected topology for a business service, click the <count> Business Services link. 
   The <entity> List page shows the list of entity names and its other attributes received from ServiceNow. For information about entities in the infrastructure, see Managing your IT infrastructure..

3. Click the entity name to view its topology.

The following figures show the topology for the Blackberry service in the ServiceNow UI and in the BMC Helix Discovery UI:

To view services in BMC Helix AIOps

1. In BMC Helix AIOps, go to the Services page.
   This page shows the Blackberry_Service. 
   
   
2. To view the impact on the service, hover over the service.
   The impact score in percentage and Situations, events, incidents, or configuration items (CIs) associated with a service are displayed.  
3. Click the service to view the health summary, causal analysis, health insights, and other key metrics of interest.
