In KIX4OTRS exists a feature, that you can visualize the Link structure in your CMDB.
Premise is, that the package libgraphviz-perl is installed on your server.
But by default, the LinkGraph feature is disabled!
To enable it, set the marker in the following SysConfig-Parameter:
AgentITSMConfigItemZoomBackend###0130-LinkGraph (under: KIX4OTRS-ITSM -> Frontend::Agent::ITSMConfigItem::ViewZoomTabLinkGraph).
