This appendix contains information about how SL1 and ServiceNow discover and model out different technologies, using VMware as an example. The VMware example explains how the differences between the systems requires rules be configured to bridge the gap between SL1 and ServiceNow.
Overview
Different platforms do not model topology the same way. The default Customer Specific CI relation overrides delivered with the "ServiceNow CMDB" SyncPack provides several topology mappings by default. Existing customers upgrading to new versions of these mappings will not override any mappings that are already set.
The following topics explain how SL1 and ServiceNow model topology differently and the mappings that are provided in this SyncPack.
The Discovery and Service Mapping Patterns application (sn_itom_pattern) plugin is required to align with your VMware mapping requirements.
VMware vCenter
The following table lists the Class mappings that are delivered by default. These are the same Class mappings that are used in Service Graph solution.
The VMware | vCenter device class is mapped to the Cloud Service Account class and not the vCenter class directly. The default mapping adheres to ServiceNow Cloud Management Relationships.
