Create the principal class recommendation criteria property

Create the sn_cmdb_advisor.principal_class_recommendation_criteria system property to filter which CI classes CMDB success advisor considers when generating principal class recommendations for the Data Foundations advisor.

Before you begin

Role required: admin

About this task

This property does not exist by default. Without it, CMDB success advisor generates recommendations based on CI class activity in task records. Create this property on instances with no prior task activity, where task-based recommendations produce no results. Setting the value to PREDEFINED tells CMDB success advisor to recommend a standard set of commonly managed CI classes instead.

Procedure

Set the application scope to CMDB success advisor using the application picker.
In the navigation filter, enter sys_properties.list and press Enter.
Select New.
Fill in the following fields.

Field	Value
Name	sn_cmdb_advisor.principal_class_recommendation_criteria
Type	string
Value	`PREDEFINED` Tells CMDB success advisor to recommend a standard set of commonly managed CI classes: Computer \[cmdb\_ci\_computer\], Server \[cmdb\_ci\_server\], Database \[cmdb\_ci\_database\], Cloud Database \[cmdb\_ci\_cloud\_database\], Virtual Machine Instance \[cmdb\_ci\_vm\_instance\], and IP Router \[cmdb\_ci\_ip\_router\].

Select Submit.

Result

CMDB success advisor uses the predefined set of CI classes as recommendations on instances where task history produces no results.
