Formatting options/variables support

[Botship]

The examples in docs (http://docs.grafana.org/reference/templating/) are like: $ Example: apps.frontend.$server.requests.count [[varname]] Example: apps.frontend.[[server]].requests.count

Application Insights based data source exposes metrics like requests/count requests/duration

How can "/" be incorporated in the variables? I tried doing client/$model However it does not work, and shows up no dimensions in dropdown.

Also, special variable ** All ** has no effect.

Any pointers, tutorial for this querying/variables would be great.
