嵌套循环内的平均温度

Question

我正在尝试编写一个脚本，该脚本使用OpenHardwareMonitor获取CPU温度，如果它在给定的持续时间内平均超过某个阈值，则会发出警报。

获取当前温度是完美的，但我正在努力将它们平均，因为在一些系统上可能有一个或多个CPU，所以我不能只记录每分钟的温度，并除以多少分钟已经过去，下面是我得到的最好的(这不工作)，请一些仁慈的灵魂帮助我看看我哪里错了？

$tempThreshold = 80 # Will alert if average temperature is above this
$minutes = 3 # Duration in minutes to test for

start-process "$env:SystemRoot\TEMP\OpenHardwareMonitor\openhardwaremonitor.exe"

# Loop each minute
for ($i=1; $i -le $minutes; $i++) {

    $arrSensors=@{}
    if ((Get-WmiObject -Namespace "Root\OpenHardwareMonitor" -Query "SELECT * FROM Sensor WHERE Sensortype='Temperature'" | ? {$_.Name -match 'CPU Package'}).value) {
        Get-WmiObject -Namespace "Root\OpenHardwareMonitor" -Query "SELECT * FROM Sensor WHERE Sensortype='Temperature'" | ? {$_.Name -Match "CPU Package"} | % {$arrSensors[$_.Name]=$_.Value}
    } else {
        Get-WmiObject -Namespace "Root\OpenHardwareMonitor" -Query "SELECT * FROM Sensor WHERE Sensortype='Temperature'" | ? {$_.Identifier -match 'cpu/'} | % {$arrSensors[$_.Name]=$_.Value}
    }


    $temps = foreach ($sensor in $arrSensors.getEnumerator()) {
        Start-Sleep -Seconds 60
        $temp = $temp+$sensor.value
        }
}

# Alert if average above threshold
if ($temps/$minutes -gt $tempThreshold) {
    Write-Host "Alert function here"
    }

我也在寻找在windows上监控cpu温度的方法。我的后端是grafana和influxdb。使用欧姆和wmi是非常占用cpu的，我找到了https://github.com/nickbabcock/OhmGraphite#influxdb-configuration。此应用程序基于ohm，但将数据直接发送到influxdb (不需要昂贵的wmi调用)。也许这也是你感兴趣的。使用grafana，您可以对该值进行平均并在其中设置阈值。

但是-也许这对你来说不是一个选择，所以这里的脚本使用欧姆应用程序来获得平均值。这个脚本的缺点是，这个脚本会运行2分钟--所以你不会每分钟收到一次警报(除非你用一分钟的appart运行它两次(这可以使用计划的任务很容易地设置)。

$tempThreshold = 80 # Will alert if average temperature is above this
$minutes = 3 # Duration in minutes to test for

start-process "$env:SystemRoot\TEMP\OpenHardwareMonitor\openhardwaremonitor.exe"

$counter = 0
$sum = 0

while($counter -lt $minutes) {
    $cpuArray = Get-WmiObject -Namespace "Root\OpenHardwareMonitor" -Query "SELECT * FROM Sensor WHERE Sensortype='Temperature'"
    
    if($cpuArray | where name -like 'cpu package*') {
        $cpuTempArray = $cpuArray | where name -like 'cpu package*'
    } else {
        $cpuTempArray = $cpuArray | where name -like 'cpu core*'
    }
    
    foreach($cpuTemp in $cpuTempArray){
        $sum += $cpuTemp.value
    }
    
    $counter++
    if($counter -ne $minutes) {
        Start-Sleep -Seconds 60
    }
}

$average = $sum/($counter*$cpuTempArray.Count)

# Alert if average above threshold
if($average -gt $tempThreshold) {
    Write-Host "Alert function here"
}

正如我提到的另一个答案，另一个脚本运行一次，IMHO不能被视为“监控”-就像“每当达到阈值时发出警报”-就像每分钟一样。

下面的脚本在无限循环中运行。它收集设定的数据量($minutes)，平均每分钟。您可能希望将其更改为存储$valueArray中所有cpus的最大值，然后取该值的平均值。

$tempThreshold = 80 # Will alert if average temperature is above this
$minutes = 3 # Duration in minutes to test for

Start-Process -FilePath "$env:SystemRoot\TEMP\OpenHardwareMonitor\openhardwaremonitor.exe"
$valueArray = [System.Collections.ArrayList]@()

while($true) {
    # keep only #no of values in array specified in $minutes
    if($valueArray.Count -gt $minutes) {
        # remove oldest entry from array
        $valueArray.RemoveAt(0)
    }

    if($valueArray.Count -eq $minutes) {
        $average = ($valueArray | Measure-Object -Sum).Sum/$minutes

        # Alert if average above threshold
        if($average -gt $tempThreshold) {
            Write-Host "Alert function here"
        }
    }

    $sensorArray = Get-WmiObject -Namespace "Root\OpenHardwareMonitor" -Query "SELECT * FROM Sensor WHERE Sensortype='Temperature'"

    if($sensorArray | where name -like 'asdf cpu package*') {
        $cpuTempArray = $sensorArray | where name -like 'cpu package*'
    } else {
        $cpuTempArray = $sensorArray | where name -like 'cpu core*'
    }

    $counter = 0
    $sum = 0
    foreach($cpuTemp in $cpuTempArray) {
        $counter++
        $sum += $cpuTemp.value
    }
    $currentAverageTemp = $sum/$counter

    $valueArray.Add($currentAverageTemp)

    Start-Sleep -Seconds 60
}
