With the recent development of Internet technologies, various web browser‐based applications and services, such as Google and Facebook, are provided. Although many web applications and services make life more efficient for users, they may become unavailable for various reasons. This can have substantial negative impacts on both users and service providers. 24/7/365 web services are especially critical in enterprise environments for establishing their business continuity. For this reason, real‐time service monitoring is the most vital factor for web application providers. Various methods to monitor web applications reliability have been proposed over the past years. However, existing approaches concentrate more on functional testing rather than considering the users perspective. Also, they cannot monitor web applications that rely on web browser application programming interfaces (APIs) or client programmes. In this paper, we propose a novel approach called SAM, which can pinpoint web application failures, including those that require browser APIs or client programmes. We describe the implementation of the SAM system and present the results of an empirical evaluation of a real‐world web application

自动监视Web应用程序的服务可靠性：一种基于仿真的方法

随着Internet技术的最新发展，提供了各种基于Web浏览器的应用程序和服务，例如Google和Facebook。尽管许多Web应用程序和服务使用户的生活更加高效，但是由于各种原因，它们可能变得不可用。这可能会对用户和服务提供商产生重大负面影响。24/7/365 Web服务在企业环境中对于建立其业务连续性尤其重要。因此，实时服务监视是Web应用程序提供商最重要的因素。过去几年中已经提出了各种监视Web应用程序可靠性的方法。但是，现有方法更多地集中在功能测试上，而不是考虑用户的角度。也，他们无法监视依赖于Web浏览器应用程序编程接口（API）或客户端程序的Web应用程序。在本文中，我们提出了一种称为SAM的新颖方法，它可以查明Web应用程序失败，包括那些需要浏览器API或客户端程序的失败。我们描述了SAM系统的实现，并给出了对实际Web应用程序的经验评估结果
