How to install and configure apps on multiple clusters

I though the point of using Rancher is was to simplify the management of clusters. But actually my feeling it’s just to simplify the access to individual cluster.

I’m surprise that I cannot center the configuration of monitoring and logs from the Global view. I still have to go in each cluster and configure it one by one.

I cannot believe I’m doing it right but I cannot find a good documentation about it. Any tips?
