Hi,
What does "2nd stage" refer to? May we know the detailed alert information? If we tried from web browser, it seems the Web Application Availability Monitoring should be ok.
Web Application Availability Monitoring
Monitor the availability of one or more web application URLs and run these monitoring tests from internal locations.
Web Application Transaction Monitoring
Monitor the availability, operation, and performance of a web application.
Hope the above information helps.
