Installation - Mapping
There are several pieces to set up, two SCOM Management Packs from Cookdown, a lightweight IIS web application, and a number of management packs (the number depends on whether you plan to use Squared Up’s dashboarding capabilities, or simply use the tool for Service Mapping).
Cookdown Management Packs
There are two Management Packs from Cookdown to be imported:
Cookdown Licensing - allows product licenses to be stored
Cookdown ServiceNow Connector - pushes SCOM objects into ServiceNow as CIs along with Business Services
Additional Setup steps
In addition to setting up SquaredUp, the Cookdown ServiceNow Connector + Licensing MPs you will need to configure Identification and Reconciliation in ServiceNow to accept Application/Business Services by creating an Identification Rule and Identifier Entry for them. Full instructions on how to do this are here.
