This article explains how to set NinjaOne as a discovery source in ServiceNow.

Environment

  • NinjaOne Integrations
  • ServiceNow

Description

According to ServiceNow documentation (external), ServiceNow Discovery is an automated process that continuously scans and identifies all the components within the IT infrastructure. It plays a crucial role in maintaining an accurate and up-to-date CMDB 360 with the information it finds.

Adding NinjaOne as a discovery source allows you to clearly differentiate NinjaOne devices in ServiceNow, which improves configuration management database (CMDB) identification and reconciliation operations. 

Before configuring the integration settings in NinjaOne for ServiceNow, you must enable it. If you have not done so already, refer to Enabling the ServiceNow Integration for instructions. 

NinjaOne as a Discovery Source

This section explains how to customize the value of the discovery source. 

By default, the NinjaOne CMDB sync uses ImportSet. If NinjaOne is available in the ServiceNow discovery source choice list, the NinjaOne CMDB sync will use it.
  1. Log in to your ServiceNow instance. 
  2. Enter "System Definition" in the Filter navigator search field.
