Generally for a system to pass commissioning it has to be all green, and if it starts event bombing after you're going to be chewed.
I have never seen a piece of new equipment that ever gets to an All Green state, before, during or after commissioning. I frequently recommend that we do not allow the commissioning team to leave until they can get it to that state but it has yet to happen.
