-// These functions takes parsed data (on one peer connection) from the
-// peerConnectionDataStore object that is backing webrtc-internals and prints
-// metrics they consider interesting using testing/perf/perf_test.h primitives.
-// The idea is to put as many webrtc-related metrics as possible into the
-// dashboard and thereby track it for regressions.
-//
-// These functions expect to run under googletest and will use EXPECT_ and
-// ASSERT_ macros to signal failure. They take as argument one peer connection's
-// stats data and a |modifier| to append to each result bucket. For instance, if
-// the modifier is '_oneway', the rtt stat will be logged as goog_rtt in
-// the video_tx_oneway bucket.
-// If |video_codec| is a non-empty string, the codec name is appended last for
-// video metrics, e.g. 'video_tx_oneway_VP9'.
