Service Mapping is available under the ITOM Visibility subscription and requires activation by ServiceNow personnel.

## Before you begin

Role required: none

To purchase a subscription, contact your ServiceNow account manager.
The account manager can arrange to have the plugin activated on your organization's
production and subproduction instances, generally within a few days.

If you don't have an account manager, decide to delay activation
after purchase, or want to evaluate the product on a subproduction instance without
charge, follow these steps.

Role required: admin

## About this task

The following plugins are activated automatically when the Service Mapping plugin (com.snc.service-mapping) is activated:

* Discovery (com.snc.discovery)  
  Note:  
  If you're activating the Discovery plugin for the first time in the Yokohama release, install the Discovery (com.snc.discovery) plugin first, then install the Discovery and Service Mapping Patterns (com.sn_itom_pattern) plugin version 1.0.52 for Cloud Discovery to work. You can then upgrade to Yokohama.
* Pattern Designer (com.snc.pattern.designer)
* Cloud Provisioning and Governance Core (com.snc.cloud.core)
* Performance Analytics -- Content Pack -- Service Mapping (com.snc.service-mapping.pa.content)
* Event Management and Service Mapping Core (com.snc.service-watch)  
  Note:  
  The Event Management and Service Mapping Core (com.snc.service-watch) plugin is different from the Event Management plugin (com.glideapp.itom.snac).
