Configure Service Graph Connector for ExtraHop
Set up a REST message and scheduled jobs to import ExtraHop data into your CMDB.
Before you begin
Important: ServiceNow hosted Service Graph Connector for ExtraHop is now deprecated and no longer supported or available for new activation. ExtraHop hosted Service Graph Connector for ExtraHop provides the latest experience for this functionality. For details, see the Deprecation Process [KB0867184] article in the Now Support Knowledge Base.
To use this Service Graph Connector, you need a subscription to a Subscription Unit that is based in the IT Operations Management (ITOM) Visibility application or in the ITOM Discovery application. As defined in the section titled "Managed IT Resource Types" in ServiceNow Subscription Unit Overview for your subscription, for managed IT resources that are created or modified in the CMDB by this Service Graph Connector, but that aren’t yet managed by ITOM Visibility or ITOM Discovery, these resources will increase Subscription Unit consumption from that application. Review your current Subscription Unit consumption within ITOM Visibility or ITOM Discovery to ensure available capacity.
