Hi @Pradeepkr
Here are key aspects to consider for CMDB optimization along with methods:
CSDM Alignment:
- Use of CSDM Data Foundations Dashboard: If the CMDB and CSDM Data Foundations Dashboard plugin is activated, utilize this dashboard to gain insights on improving CSDM alignment. It includes metrics and URLs to detailed playbooks on enhancing these metrics.
- Understanding CSDM: Before making optimization recommendations, thoroughly read the CSDM 4.0 white paper to understand its guidelines.
- Data Analysis: Analyze the data already populated in various CMDB tables, particularly those related to services. Engage with service owners and application owners to ensure the data is correctly populated according to CSDM 4.0 guidelines.
CMDB Data Quality:
- CMDB Data Foundations Dashboard: Use this dashboard to get insights on improving CMDB data quality.
- CMDB Health Metrics: Configure health metrics for completeness, correctness, and compliance to identify data quality issues such as missing data, duplicate CIs, stale CIs, and orphan CIs. The CMDB health dashboard provides insights on these issues.
- Remediation Methods: Implement deduplication tasks to address duplicate CIs. Refine identification rules for CI classes with high numbers of duplicates and set reconciliation rules for CI classes populated by multiple methods. For more information, refer to the identification and reconciliation engine (IRE).
CMDB Governance:
- Documentation: Maintain detailed documentation covering CMDB processes, procedures, policies, CI lifecycle management, RACI for ongoing management, key CI classes, data population methods, naming conventions, access rights, interaction with other processes, audit methodology, and reporting & dashboards.
- CI Class Ownership: Identify owners for each CI class populated in the CMDB. Use data certification for periodic validation of critical attributes, especially those populated manually in important CI classes.
CMDB Automation:
- Automated Data Population: Automate CMDB data population using ServiceNow Discovery and integration with third-party tools (e.g., SCCM, Intune, JamF). Use the Service Graph Connector for integrations as it utilizes the Identification and Reconciliation Engine (IRE).
- Bulk Manual Data Imports: For bulk manual data imports, use Integration Hub ETL, which also goes through the IRE.
Asset & CI Management:
- Definition and Synchronization: Clearly define what will be managed primarily as an asset and what as a CI. Establish synchronization of Asset-CI attributes and statuses according to organizational requirements.
