Hi Alberto,
As you know, Kibana is not included as part of Cloud Pak for Business Automation. Kibana must be supplied by customer, no longer installed by default.
In the other hand, for each emitter includes OOTB dashboards, visualizations and searches.

You could have a look on Installation of Cloud Pak for Business Automation on containers - Apollo one-shot deployment.
It is not an official IBM documentation although it is very useful and kibana is deployed on this deployment.
