Service Graph Connectors are predefined, vendor-specific integrations that import and synchronize external data with the ServiceNow CMDB. They are generally delivered through the ServiceNow Store and use standardized mappings, supported class models, source tracking, and Identification and Reconciliation Engine processing. This reduces the amount of custom scripting and transformation logic required to integrate third- party platforms.
Agent Client Collector is an agent-based inventory and telemetry collection mechanism. IRE identifies incoming CIs and controls how authorized sources update CMDB attributes, but it is an underlying data- processing engine rather than a packaged external-system integration. Service Mapping discovers and models Application Service dependencies; it is not a library of predefined third-party connectors.
The Data Foundations material describes Service Graph Connectors as prebuilt Store integration solutions requiring minimal customization. It also identifies them as the preferred method for third-party CI ingestion when minimizing technical debt and maintaining upgrade compatibility are priorities.
