Question

我正在尝试显示no.of进程计数。条件是我有一个父进程ID和子进程，我能够检索并显示父进程和子进程，但我想显示与父进程有关的子进程的计数。

请找到我放入的脚本。

Write-Host "ADS services with Java processes"
Invoke-Command -Computer SM06388.dom1.e-ssi.net -ScriptBlock {
    Get-WmiObject -Class Win32_Service -Filter "name='OpenLink_ADS_Fenix_PCT'"
} | ForEach-Object {
  if ($_.State -eq "running") {
    Write-Host $_.PSComputerName $_.Name $_.State $_.StartMode -  ForegroundColor green
    Get-WmiObject -Class Win32_Process -Filter "Name='java_svc_wrapper.exe'" | ForEach-Object {
      Get-WmiObject Win32_Process -Filter  "ParentProcessId=$($_.ProcessId)"
    } | Format-Table ProcessName,ProcessId,Handle,ParentProcessId -Auto
  } else {
    Write-Host $_.PSComputerName $_.Name $_.State $_.StartMode -ForegroundColor red
  }
}

我用脚本输出的输出粘贴在

下面

ADS services with Java processes
sm06388.dom1.e-ssi.net OpenLink_ADS_FENIX_PCT Running Auto

ProcessName ProcessId Handle ParentProcessId
----------- --------- ------ ---------------
java.exe        12164 12164             5520
java.exe         9392 9392              5520
java.exe        12892 12892             5520
java.exe        10396 10396             5520
java.exe         9868 9868              5520
java.exe        11584 11584             5520
java.exe        14760 14760             5520
java.exe         9740 9740              5520
java.exe        12232 12232             5520
java.exe        16432 16432             5520
java.exe        15688 15688             5520

这里我试图只显示进程的计数。任何人都可以帮我如何显示此计数。

Answer 1

它可能是一个额外的调用，但尝试Get-Process，显式查找有问题的processName并计算结果：

(Get-Process -Computer hostname.com -Name 'javaw').count

Answer 2

将它们添加到数组中，并显示数组长度（或将它们分组）：

$results = @()

write-host "ADS services with Java processes"
invoke-command -computer SM06388.dom1.e-ssi.net -scriptblock {
    get-wmiobject -Class win32_service -Filter "name='OpenLink_ADS_Fenix_PCT'"
} | foreach-object {
    if ($_.State -eq "running") {
        write-host $_.PSComputerName  $_.Name $_.State $_.StartMode -  ForegroundColor green
        Get-WmiObject -Class Win32_Process -Filter "Name='java_svc_wrapper.exe'"| 
        ForEach-Object {
            $results += Get-WmiObject Win32_Process -Filter  "ParentProcessId=$($_.ProcessId)"
        }
    }
    else {
        write-host $_.PSComputerName $_.Name $_.State $_.StartMode -ForegroundColor red }
    }

    $results

Answer 3

感谢Maigi和4c74356b41。在你的帮助下我弄明白了。

$results = @()

write-host "ADS services with Java processes"
invoke-command -computer SM06388.dom1.e-ssi.net -scriptblock {get-wmiobject   -Class win32_service -Filter "name='OpenLink_ADS_Fenix_PCT'"} | foreach-object {
if ($_.State -eq "running") 
{write-host $_.PSComputerName  $_.Name $_.State $_.StartMode -   ForegroundColor green
Get-WmiObject -Class Win32_Process -Filter "Name='java_svc_wrapper.exe'"|     ForEach-Object{
$results += (Get-WmiObject Win32_Process -Filter  "ParentProcessId=$($_.ProcessId)").count} 
Write-host "No.of Child Java process $results" -ForegroundColor green
}
else 
{write-host $_.PSComputerName $_.Name $_.State $_.StartMode -ForegroundColor  red }
}

预期产出：

ADS services with Java processes
sm06388.dom1.e-ssi.net OpenLink_ADS_FENIX_PCT Running Auto
No.of Child Java process 11

尝试使用PowerShell获取进程数
