windows - Shell script that monitors CPU usage and terminates services with high CPU utilisation

We have a Windows 2003 server where 3 services are running constantly. Sometimes these services consume over 90% CPU. Restarting these services returns normalcy. I need a script/program that will constantly monitor CPU usage and if usage is high then restart those services.

After a bit of research I found this script to monitor CPU usage from Technet.

Script to monitor CPU usage:

(get-counter -Counter "\Processor(_Total)\% Processor Time"
-SampleInterval 1 -MaxSamples 10 |
    select -ExpandProperty countersamples | select -ExpandProperty
cookedvalue | Measure-Object -Average).average

This monitors the CPU usage for 10 seconds and then displays the averaged output.

Also from Stack Overflow and Server Fault I found the scripts to restart Windows services. (Which one is better?)

Now all I need is for the CPU usage script to call the service restart scripts when the condition that usage is >90% is met. Any help would be appreciated.

Answer

Just for the record..here's the answer:

$cpuutil=(get-counter -Counter "\Processor(_Total)\% Processor Time" -SampleInterval 1 -MaxSamples 5 |
    select -ExpandProperty countersamples | select -ExpandProperty cookedvalue | Measure-Object -Average).average
If ($cpuutil -ge 90)
{Restart-Service MyService1, "My Service2", MyService3}
Else
{Exit}
