Overview

CSDM Validator checks your synced CMDB model against configured Common Service Data Model rules. Use it to identify service modeling gaps, invalid relationships, and structural issues that affect reporting and impact analysis.

When To Use It

Use CSDM Validator when:

  • you prepare for CSDM cleanup
  • you validate service models after a sync
  • you review relationship quality
  • you must confirm whether CSDM Workbench changes are necessary
  • you create remediation candidates for governed review

What It Checks

Validation can include:

  • expected service layers
  • valid relationship patterns
  • missing required relationships
  • invalid or unexpected relationship direction
  • service model completeness
  • class-specific rule violations
  • complete CSDM life cycle stage and life cycle stage status pairs

The exact rule set depends on configured CSDM rules and synced data.

For service records, the validator displays Life cycle stage and Life cycle stage status from the ServiceNow service class. These are the CSDM lifecycle values; a plain operational or install status does not replace the pair. A missing or incomplete pair appears as a warning with a recommendation to update both fields in ServiceNow.

Run Validation

  1. Open CSDM Validator.
  2. Confirm the active environment.
  3. Run or refresh validation.
  4. Review violations by severity, class, or service.
  5. Open individual findings for details.

Validation quality depends on the ServiceNow data currently synced into cmdbx. If the data looks stale, review Settings > Sync Status before interpreting results.

Review Violations

For each violation, review:

  • affected CI or service
  • rule that failed
  • expected relationship or model structure
  • severity
  • supporting evidence
  • recommended next action

Not every violation should be fixed immediately. Prioritize high-impact services and issues that affect change planning or operational visibility.

Route To Remediation

When a violation needs formal tracking:

  1. Confirm the issue is valid.
  2. Create or route a remediation candidate.
  3. Open Remediation Workbench.
  4. Review, approve, reject, or stage the candidate.

Use CSDM Workbench for modeling work when the correction involves service structure.

Common Review Questions

Is the violation caused by missing sync scope?

If a required related CI is not synced, the validator may report a gap. Check CI class scope in Settings > Sync Config.

Is the relationship wrong in ServiceNow?

If the source relationship is wrong, correct it through your ServiceNow governance process or an approved cmdbx write-back workflow.

Is the service model incomplete?

Use CSDM Workbench or AI Discovery to help review and improve service modeling.
