Hi all,

My problem is to achieve a color change display by using LED widget in css boy opi to determine whether the network communication problem occured. 

To achieve this goal, I want to use "ping" command for some ip address ; and If the network communication failed determined by "ping" command then

the LED displays red and "Network communication failed !" in text widget, otherwise the LED color is green.

Maybe this can be done by writing script, but I don't know how to do this in css boy opi or anyother methods to achieve my goal.

Could anyone please help me and thanks in advance !
