在 Amazon 日志中查看文本 CloudWatch 日志

Amazon Lex 将您的对话文本日志存储在亚马逊 CloudWatch 日志中。要查看日志，您可以使用 CloudWatch 日志控制台或 API。有关更多信息，请参阅 Amazon Logs 用户指南中的使用筛选模式搜索CloudWatch 日志数据和 CloudWatch 日志见解查询语法。

您也可以使用 CloudWatch 控制台或 API 来查看日志条目。要查找日志条目，请导航到为该别名配置的日志组。您可以在 Amazon Lex 控制台中或使用 GetBotAlias 操作查找日志的日志流前缀。

用户话语的日志条目位于多个日志流中。对话中的一个话语在一个日志流中具有一个带指定前缀的条目。日志流中的条目包含以下信息。
