Sometimes you need to monitor your Flex application and get all the info dealing with the usage of the application.
Surfing the web I found this nice component.

Flex Google Analytics Magic component will now allow you to track all of your Flex Application activities through Google Analytics. The magic is that you only have to write one line of code in your Flex application to enable this if you use this component. The Flex Google Analytics Magic component will automatically track all user navigation clicks, button click, check boxes, radio buttons and a number of other controls within your app automatically.

Nice stuff!!!
