From AlertFox Website Monitoring
Here is a collection of websites that were officially "up," but did not work properly. With each failure, we include tips on how to detect such problems with the AlertFox Transaction Monitoring iMacros Sensors.
Script Failure
Undetected script error on a website. Use the iMacros ONERROR...CONTINUE=NO command to report such issues with AlertFox.
Video Failure
The video player on the website of a popular German TV station website failed under high load and was down the whole weekend until Monday. Use the iMacros Image Recognition feature to detect issues with Flash Player (and Flash applets in general).
Sign-Up Page Failure
Here, the website itself was up, but the sign-up page showed a syntax error. This can be detected with an iMacros Sensor that tests the full sign-up transaction.
Third-Party Script Failure
A buggy third-party script fails in IE and brings down all the websites that use it - but only in IE! We recommend monitoring the most important transactions in IE
and Firefox. Worldwide, AlertFox is the only service that offers this option.
