获取有关知识库的分析
如果你在创建 QnA Maker 服务期间已启用了 Application Insights，则 QnA Maker 会存储所有聊天日志和其他遥测数据。 运行示例查询来从 Application Insights 获取聊天日志。
注意
QnA Maker 服务将于 2025 年 3 月 31 日停用。 问答功能的较新版本现已作为 Azure AI 语言的一部分提供。 有关语言服务中的问答功能，请参阅问答。 从 2022 年 10 月 1 日开始，你将无法创建新的 QnA Maker 资源。 有关将现有 QnA Maker 知识库迁移到问题解答的信息，请参阅迁移指南。
转到 Application Insights 资源。
选择“Log Analytics”。 此时将打开一个新窗口，可以在其中查询 QnA Maker 遥测数据。
粘贴以下查询并运行它。
requests | where url endswith "generateAnswer" | project timestamp, id, url, resultCode, duration, performanceBucket | parse kind = regex url with *"(?i)knowledgebases/"KbId"/generateAnswer" | join kind= inner ( traces | extend id = operation_ParentId ) on id | where message == "QnAMaker GenerateAnswer" | extend question = tostring(customDimensions['Question']) | extend answer = tostring(customDimensions['Answer']) | extend score = tostring(customDimensions['Score']) | project timestamp, resultCode, duration, id, question, answer, score, performanceBucket,KbId选择“运行”以运行查询。

注意
如果使用 Application Insights 无法正确获取日志，请确认应用服务资源上的 Application Insights 设置。 打开应用服务资源并转到 Application Insights。 然后请检查它是已启用还是禁用。 如果为禁用，请启用它，然后应用。
