Alarm when offsite office goes down.
I have many off site offices. I usually do a basic ping to determine if they are on line when there is a problem. I am looking for automated software (free preferably) or a method with available tools to give me a message or some type of alarm when any specific office goes offline.
Is there software that you can draw a map starting from the center location to all external buildings that will show a green line when online and a red line when the building is offline?
