Hi @shivaadapa ,
- Discovery patterns fail to gather key data (such as serial numbers, names, and configuration files). These failures may be due to the logic used in the pattern or a credential failure.
- CI Identifiers are configured incorrectly.
- Data is entered incorrectly (such as typographical errors, failure to check if a CI already exists)
- CI naming conditions, or processes for retiring hardware, aren't followed.
- Failures occur when importing or integrating dataNavigate to System Definition > Business Rules. Set the filter condition to Name *Create Asset on Insert, and select the Active option on the Status attribute
2)Discovery identifies the source of the data of a CI. Specially, it uses the value in the discovery source (discovery_ source) field in the CI record.
With this value, the platform or application can use the rules of the IRE. These rules provide fine-tuned control over multiple sources of discovered data.
If the discovery source field is empty (unpopulated), Discovery can't identify the source of the data in the CI. This means you won't be able to take full advantage of the IRE to maintain the accuracy your data.
Open Cmdb_ci_server.LIST and then configure list layout and bring Discovery Source column to list view and check what all empty not populated from IRE
3)Duplicate CIs can be caused by the following:- Discovery patterns fail to gather key data (such as serial numbers, names, and configuration files). These failures may be due to the logic used in the pattern or a credential failure.
- CI Identifiers are configured incorrectly.
- Data is entered incorrectly (such as typographical errors, failure to check if a CI already exists)
- CI naming conditions, or processes for retiring hardware, aren't followed.
- Failures occur when importing or integrating data
Remediation tasks that you need to address can occur due to a lack of:
- CMDB data ownership
- Enough people on the Configuration Management team
- Diligence for remediating duplicate CI tasks
- Knowledge of the CMDB Dashboard
- CMDB Dashboard governance
- Install CMDB and CSDM Data Foundations Dashboard from the ServiceNow App Store
- Navigate to the CMDB Data Foundations Dashboard module in the left navigation menu
- Select the Data Management Practices tab
- Select the Unhandled Duplicate CIs report to view a list of duplicate CIs.
- Orphan CI's.4)
OOTB audit on the CMDB Health Dashboard for Orphans.
Please mark it as solution proposed and helpful if its serves your purpose. - Thanks,
