You get started with Service Mapping by configuring roles, credentials, and MID Server connections.

Setting up Service Mapping is the first stage in the Service Mapping workflow.

Setting up Service Mapping in the workflow

Service Mapping is part of the Now Platform and deploys some of its platform-wide mechanisms and features. At the same time, there are some configurations that are specific to Service Mapping only.

Warning: The Service Mapping setup for the Advance Release is different from the standard Service Mapping setup.
Perform the following tasks in the exact order they are listed below:
  1. Request Service Mapping.
  2. Install Service Mapping Plus.
  3. Install and configure MID Server. MID Servers, which are located in the enterprise private network, facilitate communication between servers on the network and some ServiceNow applications, such as Service Mapping, and Discovery. For more information, see MID Server configuration for Service Mapping.
  4. Verify that Discovery is set up and runs horizontal discovery as expected.
  5. Configure credentials required for host discovery.
  6. Configure credentials required for Service Mapping to access applications inside your organization private network. See Prerequisites for performing top-down discovery using Service Mapping.
  7. If your organization network contains load balancers running on a Linux host, create a discovery behavior for load balancers.
  8. Grant the following Service Mapping roles to relevant users:
    service_mapping_admin

    Sets up the Service Mapping application. Maps, fixes, and maintains service instances. Also performs advanced configuration and customization of the product. Assign this role to application administrators.

    service_mapping_user

    Views maps for operational service instances to plan change or migration, as well as analyze the continuity and availability of services. Assign this role to application users.

    sm_app_owner

    Provides information necessary for successful mapping of a service instance. Once a service is mapped, this user reviews the results and either approves it or suggests changes. Assign the sm_app_owner role to users who own service instances and are familiar with the infrastructure and applications that make up the services.

  9. Verify that Service Mapping is set up properly.
  10. If your organization has a ServiceNow deployment with customized Discovery or CMDB attributes, perform additional configuration described in KB0647574: Preparing customized ServiceNow deployments to work with Service Mapping.

In addition to the obligatory setup configurations described here, you may need to perform additional configurations after you complete the initial mapping process. For more information, see Advanced Service Mapping configuration.
