Startup parameter: alertcpulimit

Startup parameters change the behavior of the Service Manager server. You can always set a startup parameter from the server's operating system command prompt.

Parameter

alertcpulimit

Description

This parameter defines the number of standard deviations from the mean CPU usage that cause the Service Manager server to issue an alert message.

For example, suppose that a customer reports that they have set the alertperoidicschedule record to expire every 5 minutes. This means that every 5 minutes we look at the amount of CPU consumed by each process in the last 5 minutes. We take all the values and we get an average. Given all the values that make the average there is a statistical calculation called the standard deviation that returns a number that represents how far from the average each deviation is. If all of the users used between 5 and 7 cpu seconds then the standard deviation would be really small. If all the users used between 5 and 100 cpu seconds (assume the values were spread out across this range) then the standard deviation would be larger. So in the last case lets assume the average was 50 and the standard deviation was 3, then we would report on any user who used more than 65 seconds (50 + 5*3).
