在Powershell中创建日志文件

Question

我有以下代码,目前它加载屏幕上的所有信息.我希望它登录到D:\ Apps\Logs上的日志文件.

日志文件需要具有要加载的计算机的名称 - 所以COMPUTERNAME.log

知道我怎么能这样做吗？

谢谢

$computer = gc env:computername

$onetcp = ((get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductMajorPart).tostring() $twotcp = ((get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductMinorPart).tostring() $threetcp = ((get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductBuildPart).tostring() $fourtcp = ((get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductPrivatePart).tostring()


$onedfsr = ((get-childitem c:\windows\system32\dfsrs.exe).Versioninfo.ProductMajorPart).tostring() $twodfsr = ((get-childitem c:\windows\system32\dfsrs.exe).Versioninfo.ProductMinorPart).tostring() $threedfsr = ((get-childitem c:\windows\system32\dfsrs.exe).Versioninfo.ProductBuildPart).tostring() $fourdfsr = ((get-childitem c:\windows\system32\dfsrs.exe).Versioninfo.ProductPrivatePart).tostring()

write-host TCPIP.sys Version on $computer is: "$onetcp.$twotcp.$threetcp.$fourtcp" Write-Host write-host DFSRS.exe Version on $computer is: "$onedfsr.$twodfsr.$threedfsr.$fourdfsr"

Write-Host

If (get-wmiobject win32_share | where-object {$_.Name -eq "REMINST"}) {   Write-Host "The REMINST share exists on $computer" } Else {   Write-Host "The REMINST share DOES NOT exist on $computer - Please create as per standards"  }   Write-Host

$hotfix1 = Get-HotFix -Id KB2450944 -ErrorAction SilentlyContinue $hotfix2 = Get-HotFix -Id KB2582284 -ErrorAction SilentlyContinue $hotfix3 = Get-HotFix -Id KB979808 -ErrorAction SilentlyContinue

If ($hotfix1) {     Write-Host "Hotfix KB2450944 is installed"
-BackgroundColor Green -ForegroundColor Black   } else {    Write-Host "Hotfix KB2450944 is NOT installed - Please ensure you install this hotfix" -ForegroundColor "red"   }


If ($hotfix2) {     Write-Host "Hotfix KB2582284 is installed"
-BackgroundColor Green -ForegroundColor Black   } else {    Write-Host "Hotfix KB2582284 is NOT installed - Please ensure you install this hotfix" -ForegroundColor "red"   }

If ($hotfix3) {     Write-Host "Hotfix KB979808 is installed"
-BackgroundColor Green -ForegroundColor Black   } else {    Write-Host "Hotfix KB979808 is NOT installed - Please ensure you install this hotfix" -ForegroundColor "red"    }

Answer 1

把它放在你文件的顶部:

$Logfile = "D:\Apps\Logs\$(gc env:computername).log"

Function LogWrite
{
   Param ([string]$logstring)

   Add-content $Logfile -value $logstring
}

然后Write-host用LogWrite.替换你的电话.

一种将这些原则更进一步的功能.

1. 添加时间戳 - 没有时间戳的日志.
2. 添加一个级别(默认情况下使用INFO)意味着您可以突出显示重大问题.

3. 允许可选的控制台输出.如果您没有设置日志目的地,它只会将其抽出.

   Function Write-Log {
       [CmdletBinding()]
       Param(
       [Parameter(Mandatory=$False)]
       [ValidateSet("INFO","WARN","ERROR","FATAL","DEBUG")]
       [String]
       $Level = "INFO",
   
       [Parameter(Mandatory=$True)]
       [string]
       $Message,
   
       [Parameter(Mandatory=$False)]
       [string]
       $logfile
       )
   
       $Stamp = (Get-Date).toString("yyyy/MM/dd HH:mm:ss")
       $Line = "$Stamp $Level $Message"
       If($logfile) {
           Add-Content $logfile -Value $Line
       }
       Else {
           Write-Output $Line
       }
   }

我相信这是将屏幕上的所有内容放入文件的最简单方法。它是原生的 PS CmdLet，因此您无需在脚本中更改或安装任何内容

Start-Transcript -Path Computer.log

Write-Host "everything will end up in Computer.log"

Stop-Transcript

Answer 4

function WriteLog
{
    Param ([string]$LogString)
    $LogFile = "C:\$(gc env:computername).log"
    $DateTime = "[{0:MM/dd/yy} {0:HH:mm:ss}]" -f (Get-Date)
    $LogMessage = "$Datetime $LogString"
    Add-content $LogFile -value $LogMessage
}

WriteLog "This is my log message"

Answer 5

日志轮换的要点:https://gist.github.com/barsv/85c93b599a763206f47aec150fb41ca0

用法:

. .\logger.ps1
Write-Log "debug message"
Write-Log "info message" "INFO"

Answer 6

使用这个Log-Entry框架：

脚本：

Function Main {
    Log -File "D:\Apps\Logs\$Env:computername.log"

    $tcp = (get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductVersionRaw
    $dfs = (get-childitem C:\Windows\Microsoft.NET\Framework\v2.0.50727\dfsvc.exe).Versioninfo.ProductVersionRaw

    Log "TCPIP.sys Version on $computer is:" $tcp
    Log "DFSVC.exe Version on $computer is:" $dfs

    If (get-wmiobject win32_share | where-object {$_.Name -eq "REMINST"}) {Log "The REMINST share exists on $computer"}
    Else {Log "The REMINST share DOES NOT exist on $computer - Please create as per standards"}

    "KB2450944", "KB3150513", "KB3176935" | ForEach {
        $hotfix = Get-HotFix -Id $_ -ErrorAction SilentlyContinue
        If ($hotfix) {Log -Color Green Hotfix $_ is installed}
        Else {Log -Color Red Hotfix $_ " is NOT installed - Please ensure you install this hotfix"}
    }
}

屏幕输出：

日志文件（位于D:\Apps\Logs\<computername>.log）：

Function Main {
    Log -File "D:\Apps\Logs\$Env:computername.log"

    $tcp = (get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductVersionRaw
    $dfs = (get-childitem C:\Windows\Microsoft.NET\Framework\v2.0.50727\dfsvc.exe).Versioninfo.ProductVersionRaw

    Log "TCPIP.sys Version on $computer is:" $tcp
    Log "DFSVC.exe Version on $computer is:" $dfs

    If (get-wmiobject win32_share | where-object {$_.Name -eq "REMINST"}) {Log "The REMINST share exists on $computer"}
    Else {Log "The REMINST share DOES NOT exist on $computer - Please create as per standards"}

    "KB2450944", "KB3150513", "KB3176935" | ForEach {
        $hotfix = Get-HotFix -Id $_ -ErrorAction SilentlyContinue
        If ($hotfix) {Log -Color Green Hotfix $_ is installed}
        Else {Log -Color Red Hotfix $_ " is NOT installed - Please ensure you install this hotfix"}
    }
}
