SSAI 廣告跟踪日誌

SSAI 廣告跟踪日誌是一項新功能，旨在提供有關 SSAI 廣告運作方式的詳細信息。此功能適用於 VOD 和直播。

簡介

Brightcove 提供廣告跟踪日誌，以幫助您從獲利角度了解支持 SSAI 的直播和視頻的表現，並解決任何問題。這些日誌包括對廣告服務器的請求：廣告請求、錯誤和跟踪事件。

日誌還允許您計算性能指標：

廣告請求：向廣告服務器請求廣告的次數。
觸發的廣告跟踪事件：從 BC SSAI 服務器觸發的信標事件數。它可以是每種類型的細分：AdStart , AdComplete , AdfirstQuartile , Admidpoint , AdthirdQuartile , AdcreativeView
Ad Delivery Rate：成功的廣告請求總數/廣告請求總數的比率

設定

要啟用 SSAI 廣告跟踪日誌，您必須執行以下操作：

在您的首選區域中創建 S3 存儲桶。
為 Brightcove Support 提供您的存儲桶名稱和區域。
添加支持人員提供給您的安全策略，使 Brightcove 能夠寫入您的存儲桶。
設置 S3 存儲桶後，開始記錄廣告配置集ad_tracking_sample_percentage給你的直播廣告配置和/或你的VOD 廣告配置 .

文件格式

日誌文件將根據此架構組織在您的 S3 存儲桶中：

/yyyy/MM/dd/HH/<random-string>/<delivery stream name>-<delivery stream version>-<year>-<month>-<day>-<hour>-<minute>-<second>-<uuid>

<random-string>和</uuid>，每批都會不同，日誌以5MB或300秒的數據為批次。不同會話和作業的日誌將混合在批次中。
