Web应用程序，使有点棘手调试，因为我们不能够访问IIS或事件日志等任何建议将AP preciated。
Web Apps makes a bit tricky to debug as we don't have access to IIS or event logs etc. Any suggestion would be appreciated.
推荐答案
在Azure的Web应用程序，您就可以访问这些日志和许多其他故障排除工具。导航到//<yourwebsitename>.scm.azurewebsites.net并探讨在捻工具的选项。特别是检查工具|支持菜单选项。你需要在你的web应用程序启用日志记录第一。
In Azure Web Apps, you do have access to those logs and many other troubleshooting tools. Navigate to //<yourwebsitename>.scm.azurewebsites.net and explore your options in the Kudu tool. Especially check the Tools | Support menu option. You'll need to enable logging in your web app first.
