在Powershell中创建日志文件

71

我有下面的代码，当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-因此COMPUTERNAME.log

知道我该怎么做吗？

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"   }

日志：术语“日志”不能识别为cmdlet，脚本文件或可运行程序的名称。检查包含的名称的拼写，确认路径正确，然后重试。您也有日志功能吗？

将其放在文件顶部：

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

Function LogWrite
{
   Param ([string]$logstring)

   Add-content $Logfile -value $logstring
}

然后将您的Write-host呼叫替换为LogWrite。

谢谢-可以正常工作，但现在不显示TCPIP.sys版本-只是显示“ TCPIP.sys”-与DFSR.exe相同。我将Write-Host更改为LogWrite，但是这两个未在日志文件中显示版本。另外，您知道我每次运行时如何重新写入日志文件的想法吗？当前，它会附加日志文件。如果它每次只能创建一个新的文件，则希望这样做。谢谢。

对于对象的属性，您需要将整个对象括在括号中，并在前面加一个$。尝试将其更改为：$(TCPIP.sys)

要使日志文件每次都重新制作，您需要在顶部添加另一个部分以删除/创建该文件（如果存在）。

只是附带说明，您可以使用$ env变量将计算机名嵌入字符串中，而无需使用get-content和变量赋值。Write-Host "My local computer name is: $env:computername"

我还喜欢使用-passthrough标志，以便日志记录也输出到Shell窗口。

一种将这些原理进一步发展的功能。

  1. Add的时间戳-没有时间戳就不能有日志。
  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大问题。

  3. 允许可选的控制台输出。如果您未设置日志目标，则只需将其抽出即可。

    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所有内容放入文件的最简单方法。这是本机PS CmdLet，因此您无需在脚本中进行任何更改

Start-Transcript -Path Computer.log

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

Stop-Transcript

这应该是公认的答案。它的本机和最小。

使用非常简单。我建议添加-Append或NoClobber以其他方式覆盖日志。另请注意，它会以标题的形式输出有关进程和主机的许多内容，因此它不直接等同于屏幕上的内容，除非您使用-UseMinimalHeaderetc参数。

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"}
    }
}

您可能只想使用新的TUN.Logging PowerShell模块，它也可以发送日志邮件。只需使用Start-Log和/或Start-MailLog cmdlet开始记录，然后仅使用Write-HostLog，Write-WarningLog，Write-VerboseLog，Write-ErrorLog等即可写入控制台和日志文件/邮件。然后在末尾调用Send-Log和/或Stop-Log，瞧，您的日志记录了。只需从PowerShell库通过安装

Install-Module -Name TUN.Logging

或者只是点击链接： https //www.powershellgallery.com/packages/TUN.Logging

该模块的文档可以在这里找到：https : //github.com/echalone/TUN/blob/master/PowerShell/Modules/TUN.Logging/TUN.Logging.md

我已经玩了一段时间了，我有一些对我来说很好的东西。日志文件的编号以“ 0”开头，但保留文件扩展名。我知道每个人都喜欢为所有功能创建函数，但是我开始删除执行一项简单任务的函数。少花招，为什么要用很多词？可能会删除其他功能，并可能在其他模块之外创建功能。我将记录器脚本保留在中央共享中，并在本地副本（如果已更改）中进行复制，或者在需要时从中央位置加载它。

首先，我导入记录器：

#Change directory to the script root
cd $PSScriptRoot

#Make a local copy if changed then Import logger
if(test-path "D:\Scripts\logger.ps1"){
    if (Test-Path "\\<server>\share\DCS\Scripts\logger.ps1") {
        if((Get-FileHash "\\<server>\share\DCS\Scripts\logger.ps1").Hash -ne (Get-FileHash "D:\Scripts\logger.ps1").Hash){
            rename-Item -path "..\logger.ps1" -newname "logger$(Get-Date -format 'yyyyMMdd-HH.mm.ss').ps1" -force
            Copy-Item "\\<server>\share\DCS\Scripts\logger.ps1" -destination "..\" -Force 
        }
    }
}else{
    Copy-Item "\\<server>\share\DCS\Scripts\logger.ps1" -destination "..\" -Force
}
. "..\logger.ps1"

定义日志文件：

$logfile = (get-location).path + "\Log\" + $QProfile.replace(" ","_") + "-$metricEnv-$ScriptName.log"

我记录的内容取决于我创建的调试级别：

if ($Debug -ge 1){
    $message = "<$pid>Debug:$Debug`-Adding tag `"MetricClass:temp`" to $host_name`:$metric_name"
    Write-Log $message $logfile "DEBUG"
}

在编码方面，我可能会觉得自己有点“ hack”，所以这可能不是最漂亮的，但这是我的版本logger.ps1：

# all logging settins are here on top
param(
    [Parameter(Mandatory=$false)]
        [string]$logFile = "$(gc env:computername).log",

    [Parameter(Mandatory=$false)]
