Is it a "Down" alert or an "Up" alert? When "and when backup too" is checked SA will send an up alert every time the threshold is crossed even if it does not send a down alert because it hasn't reached the consecutive cycles limit. I see this a bit with one of our machines. I will get email saying the CPU is below 90% even though I did not get and email saying it was above 90%. There isn't any way to get around this that I know of.
