RTC 統計情報 API¶

注意

この API は実験的機能のため、正式版では仕様が変更される可能性があります。

統計情報更新のタイミングについて¶

この統計情報は、クライアントからシグナリングで送信されてくる統計情報の最新の値を返します。デフォルトでは WebSocket と DataChannel 経由のどちらも 60 秒間隔で更新されます。

間隔は以下で変更できます。

ListRtcStats¶

x-sora-target:: Sora_20211215.ListRtcStats

すべてのユーザーエージェント統計情報の一覧を取得します。

キー	型	デフォルト
local (オプション)	boolean	true

local はクラスター機能利用時に、全てのノードの情報を取得するかどうかを指定します。
