We have multiple Kamailio 4.4.x servers and I am setting up stats tracking.  I would like to track the stats for each individual Kamailio server separately like so:

The problem is that we use one common file (in version control) for our Kamailio configuration.  Thus, I can’t just hardcode the hostname into the file because it will be the same for each server.

Does anyone have a solution for me?  Is there a variable that provides the hostname or is there something else I can do?

Ideally, I’d love to be able to do something like this.
