We currently have a NewRelic ruby agent installed on our app and we use Appdex score for alerting.
We have a high frequency error class ‘ApiError’ which can spike and cause low Appdex score.
Our preference would be for the Appdex and error analytics not to take into account the ApiErrors that occurs on a 4xx http response, but keep tracking the other ApiErrors.
Is this possible? I was looking at the docs for ‘marking errors as expected’ but it wasn’t clear how we’d accomplish the above use case.
Also, is it possible to configure this through the server-side configuration (settings-server-side-agent-configuration) rather than through the ruby agent?
