Graphite templating : complex query to filter metrics


I’m using Grafana 2.4 connected to a Graphite server.

I want to create a dashboard to retrieve haproxy metrics which appear in srv.<servername>.haproxy

I would like to be able to template it so user can select to view all haproxy servers, or only some. (like this dashboard do

I can’t find a way to query *.*.haproxy and create a template variable with the second *. I’m not even sure it’s possible.

Doing ..haproxy and only getting the second node is not supported right now

Ok, thanks. Is it a Grafana limitation or a Graphite one?
