Service Graph Diagnosis

Overview

This skill provides a systematic approach to diagnosing and resolving Service Graph Connector issues in ServiceNow. It covers:

• Validating Service Graph Connector configurations and connection status
• Troubleshooting data flow from external data sources into the CMDB via cmdb_ci and cmdb_rel_ci
• Diagnosing discovery pattern failures and identification/reconciliation rule mismatches
• Analyzing import set run logs for ingestion errors
• Detecting duplicate CIs created by faulty reconciliation in cmdb_inst_duplicate
• Verifying service mapping data integrity in cmdb_ci_service and svc_ci_assoc
• Monitoring connector health, scheduling, and transformation map accuracy

When to use: When Service Graph Connectors fail to populate or update CIs, when discovery produces duplicates or missing relationships, when service maps show incomplete or stale data, or when connector integrations report errors.

Value proposition: Rapid diagnosis of service graph issues prevents CMDB data quality degradation, ensures accurate service maps for change and incident management, and reduces MTTR for integration failures.
