Hii @SP22 ,

Thank you for the reply ,

This video is not helpful , if we enable restricted software field for software models, software installations will be deleted . But we need software installations to created or updated from Tanium .  Just want to know is there any  way to restrict ServiceNow discovery from capturing software installations and its updation in CMDB.

Hello @Dharani7,

Configure Identification and Reconciliation Rules (IRE):

Purpose: Ensure only Tanium can update software CIs.

step by step gudience:

1. Navigate to:
   Configuration > CI Class Manager

2. Search for Software CI Class:
   For example, cmdb_ci_spkg.

3. Open the Class:
   Click on the class name.

4. Go to Reconciliation Rules:

   • Click the Reconciliation Rules tab.
   • Review existing rules.

5. Edit/Create Rule:

   • Set Tanium as the preferred data source for relevant attributes (e.g., version, installation date).
   • Set Discovery as a lower priority or exclude it from updating these attributes.

6. Save the Rule.

Hii @SP22 ,

Software installation[cmdb_sam_sw_install] table is not available under CI class manager , since it is not extending cmdb_ci class  so reconciliation rule cannot be applied on it.

@Dharani7  If the software installations are updated with Patterns from Discovery, find those patterns and disable them. 

Try running discovery for one server and then you can easily find the pattern in the discovery logs. 

Is tanium is updating this table through API?
