Understanding Service Impact packaging, architecture, and deployment
Service Impact 5.x for Resource Manager 5.x or 6.x is packaged as a Docker image and two ZenPacks (ZenPacks.zenoss.Impact and ZenPacks.zenoss.ImpactServer). The files are available from delivery.zenoss.com. The ZenPacks require a customized installation procedure, which is documented in this guide.
The Impact service includes the Service Impact server and database. The install process adds the service to the Infrastructure hierarchy in Control Center. Its requirements are minimal, compared to the other services in that hierarchy. The resource pool you select for the Infrastructure hierarchy easily accommodates the Impact service.
The zenimpactstate service includes the zenimpactstate daemon. In Control Center, the service is included in the Events category of the Zenoss hierarchy.
