Title graph template with two variables


I’m building a graph using templates, my datasource is influxdb, where I have a collection of network interfaces with the tags: interface name and description.

I defined as variable in the dashboard the tag “description”, this because I want it to mount the graphics based on a regex.

My problem is with title of the graphic, I need to be inserted the name of the interface and also its description, the description I already managed to make use of the variable description. I did a test also creating the various interface name, but it did not work as I wanted, in rendering the graphics the interface always gets the same name.

Does anyone know how to do this?

I thought as a contour solution I created one more tag in my influx metric concatenating the interface name and description information.
