For the things that I've work on, in addition to regular health checks, we always write custom load generators that _really_ understand the domain and were configurable to realistic traffic levels. You can always leave them running, instrument them with metrics, and plug it into your alerting infrastructure so that you can page based on "realistic" client-side observable behavior. It's a super useful addition to the occasional time you need to do a performance/scale test.

Is there a generic load tester that allows you to define enough calling information about the APIs to get the same level of value out that I described?

I am working on a scripting framework for Loadjitsu. You should be able to run custom tests with domain specific inputs
