Explanation:
Agent Client Collector (ACC) # Collects inventory and telemetry from devices using an installed agent, especially where agentless discovery is not practical.
ServiceNow Discovery # Automatically identifies devices and applications on the network and populates the CMDB with accurate, up-to-date information.
Service Graph Connectors # Facilitates integration between ServiceNow and external systems to import and synchronize CMDB data.
Service Mapping # Builds the complete topology of services and shows how they are supported by underlying infrastructure and applications.
Each ingestion product has a specific role in CMDB Data Foundations. ServiceNow Discovery is primarily agentless and discovers infrastructure, applications, and relationships across the network. Agent Client Collector is agent-based and is useful for devices that are intermittently connected, remote, restricted, or difficult to scan through traditional Discovery. Service Graph Connectors are prebuilt, governed integrations used to bring third-party data into the CMDB while aligning with IRE and ServiceNow class models. Service Mapping focuses on service topology by identifying how application services depend on infrastructure and application components. The key distinction is that Discovery and ACC collect technical inventory, Service Graph Connectors integrate external sources, and Service Mapping builds service dependency models.
