Class Configuration

By default all classes are preloaded in an inactive state. To sync data to the Service Now CMDB you must activate the classes you wish to send. Classes for multiple instances of Service Now can be configured independently. To start configuring classes for a specific instance navigate to Integrations → Service Now and select the instance you wish to configure. From the Actions menu select “Configure Syncronisation”.

From here you can see the list of the Syncronisation Definitions for each Schema. To configure the classes select a schema, navigate to the “Actions” menu and select “Configure Classes”

The following table shows the details for each column shown :

Column Name	Description	Notes

Column Name	Description	Notes
Name	ServiceNow Data Class Name

Active	uControl setting for Class active / inactive	Initial default in inactive for all classes
Attributes Mapped	Displays green when attributes are mapped.	Default attributes are mapped during setup.
Class Rules Mapped	Are filters applied to the CI class configuration	Default is no filters applied for parent tables, child tables will have OOTB filters applied.
BMC Kind	The associated node kind from BMC Discovery that will write data into the ServiceNow CI class

Class rules allow you to filter the device types from BMC Discovery that you wish to send to Service Now. These filters can be positive or negative depending on the requirement. Eg.

Send Only “Oracle Database Server” CI to the cmdb_ci_appl class:

type → Equals → “Oracle Database Server”

Send Only servers with “Prod” in the name to the cmdb_ci_server class:

name → Contains → “Prod”

The following conditions are available for all class rules :
