-// Rtc histograms can be queried through the API, getAndReset().
-// The returned map holds the name of a histogram and its samples.
-//
-// Example of |map| with one histogram:
-// |name|: "WebRTC.Video.InputFramesPerSecond"
-//     |min|: 1
-//     |max|: 100
-//     |bucketCount|: 50
-//     |samples|: [30]:1
-//
-// Most histograms are not updated frequently (e.g. most video metrics are an
-// average over the call and recorded when a stream is removed).
-// The metrics can for example be retrieved when a peer connection is closed.
