The URL screenshot is an option which performs a screen capture and produces an image displaying the visible items of a web page as they would be displayed on a computer screen by a browser.
To produce a screenshot our monitoring agent uses an application, based on the Firefox browser engine, which opens the cached page and does a screenshot of the browser screen. The screenshots are saved for future reference by the Customers and are available from different areas of the control panel. Screenshots can be produced for every last check or in the event we detect an error.
This option is currently available with our Website Performance, Full-page and Transaction monitoring services.
