Tag Based Service Map Not showing Relationships between CIs

[Mason Angus]

I am running into an issue when trying to create service maps using the tag based approach for the sake of simplicity I am showing a very simple map here. There is an entry point (tag based app service) a vm, and a storage array.  

The issue I am having is this this flat view. If I swing over to the dependency view of this VM I can see their is a relationship between the VM and this storage array. This relationship is not reflected within the map.

 

For a simple case like this, it is no big deal, but I have some apps with complex architecture with tens, if not hundreds of CIs with relationships and they are all being shown in this flat view. One of the objectives we have in using service mapping, is that our incident management is able to see dependencies in real time in the service map. I have been shown in demos that creating a "tree" dependency map is possible using the tag based approach, so am I doing something wrong or was I sold a false bill of goods? 

Thanks in advance

Hi Mason,

Traversal Rules need to be added in proper order as tag-based discovery uses these rules to find the ci's that can be mapped.

By default, the max number of active traversal is 5 and can be changed with sys_property svc_by_tags.max.traversal.rules.active.

and  you need create the traversal rules in the table svc_traversal_rules to show the relationships on the map.

Once you create the traversal rules you should be able to see the relationships on the service map.
