使用 Amazon Nova Act 实现合成监控
原标题：Implementing synthetic monitoring using Amazon Nova Act
AI 摘要
AWS 博客介绍了一种基于 Amazon Nova Act 和 Amazon Bedrock AgentCore 的合成监控方案，用多模态大模型处理 UI 截图而非 DOM 选择器来执行用户旅程验证。该方案结合 EventBridge Scheduler、AgentCore Runtime 和 Browser 工具实现无服务器调度与隔离浏览器执行，失败时通过 SNS 告警。文章称 Nova Act 在企业客户用例中对浏览器工作流准确率超过 90%，可减少传统 Selenium/Playwright 脚本的维护成本。

Implementing synthetic monitoring using Amazon Nova Act Synthetic monitoring emulates real user journeys through automated transactions. Rather than waiting for customers to encounter problems, teams continuously validate critical workflows (logins, purchases, form submissions) on a scheduled basis. With this approach, you detect problems faster when performance degrades or UI interactions break. For customer-facing businesses, especially in ecommerce, synthetic monitoring safeguards interaction
