CMDB relationship mappings

Detects CMDB relationship mappings: CMDB or dependency-map wording with relationship edges (ServiceNow relationship types or A -> B edges) and populated CI fields. Topic wording alone is discovery-only.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: the topic phrase alone is discovery-only; enforcement needs populated structure (a relationship edge (ServiceNow relationship type such as Depends on::Used by, or an A -> B edge) or a populated CI field (CI name/ID/class, parent/child, sys_id, business/application service, support group, environment)), and 85 needs two distinct structures plus independent dependency-impact (upstream/downstream, impact analysis, server roles) evidence, so policies, blank forms and training text stay below 75.

Should match

The CMDB is the source of truth for configuration items. — Discovery probe (65)
CMDB relationship export payroll-web01 -> payroll-db01 — Medium-tier probe (75) - one relationship edge
CMDB relationship export - Payroll business service CI name: payroll-web01 (class: Linux Server) payroll-web01 -> payroll-db01 Depends on::Used by: payroll-app -> payroll-web01 Support group: Enterprise Apps Impact analysis: payroll-db01 is a single point of failure for all downstream pay runs. — High-tier probe (85) - edges, CI fields and impact context

Should not match

unrelated generic text — No relevant phrase context
placeholder value 12345 — Random text should not match
Policy statement: the CMDB must be updated for every production change. — Policy text
CMDB relationship template CI name: ________ Parent CI: [insert] — Blank template
Course module 3: CMDB relationship types include Depends on::Used by and Runs on::Runs. — Training framing

Known false positives

ITSM product documentation lists relationship types. Mitigation: Guidance/training framing is excluded; 85 needs two edges plus populated CI fields.
