RedHat 7.1 - Monitor Shutdown

On my RedHat 7.1 box, I usually have monitoring software running to check if sites are up and how much data is going through it etc..

After 20 or so minutes pass, the monitor goes blank and I have to move the mouse or hit a key to get it back. Any idea how to stop it from going off at all?
