Template Variable Grafana

Hi aeckstein,
also using the new plugin in beta, I have the possibility of creating a simple graph.
But what I would like to do is to create a dashboard with generic panel e.g. “Cpu Utilisation”, “Disk”, “Mem” etc. etc. and at the top of the dashboard create the variable “host name” or “hostgroup” with a drop-down menu where you can select the host/group.

Any ideas?

Thanks!
