Is the bandwidth too low? Is the latency too high? Is the router dropping UDP packets? Is the CPU usage too high (leading WebRTC to drop frames)? Etc... It goes on and on. The stats API dumps a lot of information (too much for me to parse quickly, obviously) but even with all this information it's hard to come up with a conclusive answer to these actions.
Chrome has a very helpful chrome://webrtc-internals/ page which shows all the API calls and results
along with graphs of the status of all the media flows. 
I find this very helpful when debugging.
I haven't found an equivalent in firefox yet.
