I am making a simple script for my internship in powershell, that uses simple stuff like variables, the IF...ELSE statement, as well as Get-Counter.
$CpuLoad = "\Processor(_Total)\% Processor Time"
$Threshold = 50
Get-Counter -Counter $CpuLoad -SampleInterval 1 -MaxSamples 10
IF($CpuLoad -gt $Threshold) {
Write-Host "CPU Utilizacija ir lielaka par 50 procentiem!"
} Else {
Write-Host "Viss ok!"
}
That is the script. No matter what the CPU utilization percentage is, it will always say the ELSE write-host statement, not the IF write-host statement. Do not worry. I am not trying to cheat or anything of the sort ;). I'm simply dumb-founded as to how such a simple script can break so easily! Any help is appreciated!
CodePudding user response:
Comparing the string "\Processor(_Total)\% Processor Time"
to the number 50
doesn't make much sense.
Instead, use Where-Object
to test if any of the counter samples returned by Get-Counter
exceeds the threshold:
$CpuLoad = "\Processor(_Total)\% Processor Time"
$Threshold = 50
$samplesExceedingThreshold = Get-Counter -Counter $CpuLoad -SampleInterval 1 -MaxSamples 10 |ForEach-Object CounterSamples |Where-Object CookedValue -gt $threshold |Select-Object -First 1
if($samplesExcheedingThreshold){
Write-Host "CPU Utilizacija ir lielaka par 50 procentiem!"
} else {
Write-Host "Viss ok!"
}
