Testing Infrastructure with Gatling (general question)

Hi, we would like to use Gatling to performance test an Infrastructure consisting of i.e. Loadbalancers, the network of course an similar components.

I am guessing it would be wise to i.e. just to a simple GET to a static resource like a jpg or something and not involve any application logic?

Any one done something of a similar test and maybe got some good advice what to do and dont?
