在 Powershell 中创建日志文件

发布于 2024-12-11 03:41:42 字数 2379 浏览 0 评论 0原文

我有下面的代码,目前它加载屏幕上的所有信息。我希望它记录到 D:\Apps\Logs 上的日志文件中。

日志文件需要有它正在加载的计算机的名称 - 所以 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"   }

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"    }

I have the below code and currently it loads all the information on screen. I want it to log to a log file on D:\Apps\Logs.

The log file needs to have the name of the computer it is loading against - so COMPUTERNAME.log

Any idea how I can do this?

Thanks

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 Write-host 调用替换为 LogWrite

Put this at the top of your file:

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

Function LogWrite
{
   Param ([string]$logstring)

   Add-content $Logfile -value $logstring
}

Then replace your Write-host calls with LogWrite.

一个将这些原则进一步发展的函数。

  1. 添加时间戳 - 不能有没有时间戳的日志。
  2. 添加级别(默认使用 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,它只会将其输出。

    函数写入日志 {
        [CmdletBinding()]
        参数(
        [参数(强制=$False)]
        [ValidateSet("信息"、"警告"、"错误"、"致命"、"调试")]
        [细绳]
        $级别=“信息”,
    
        [参数(强制=$True)]
        [细绳]
        $消息,
    
        [参数(强制=$False)]
        [细绳]
        $日志文件
        )
    
        $Stamp = (Get-Date).toString("yyyy/MM/dd HH:mm:ss")
        $Line =“$Stamp $Level $Message”
        如果($日志文件){
            添加内容 $logfile -Value $Line
        }
        别的 {
            写输出$Line
        }
    }
    

A function that takes these principles a little further.

  1. Add's timestamps - can't have a log without timestamps.
  2. Add's a level (uses INFO by default) meaning you can highlight big issues.
  3. Allows for optional console output. If you don't set a log destination, it simply pumps it out.

    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 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

您还可以添加 -Append 来附加内容 [感谢 @scipilot 的提示!]

I believe this is the simplest way of putting all what it is on the screen into a file. It is a native PS CmdLet so you don't have to change or install anything in your script

Start-Transcript -Path Computer.log

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

Stop-Transcript

You can also add -Append to append instead the content [Thanks @scipilot for the tip!]

        $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"}

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

用法:

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

Gist with log rotation: https://gist.github.com/barsv/85c93b599a763206f47aec150fb41ca0

Usage:

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

我已经使用这段代码有一段时间了,我有一些对我来说很有效的东西。日志文件以前导“0”进行编号,但保留其文件扩展名。我知道每个人都喜欢为所有事情创建函数,但我开始删除执行一项简单任务的函数。为什么要使用很多词,而很少有人会欺骗呢?可能会删除其他功能,并可能从其他块中创建功能。我将记录器脚本保存在中央共享中,并在发生更改时制作本地副本,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,我可能会认为自己有点“黑客”,所以这可能不是最漂亮的,但这是我的logger.ps1 版本:

I've been playing with this code for a while now and I have something that works well for me. Log files are numbered with leading '0' but retain their file extension. And I know everyone likes to make functions for everything but I started to remove functions that performed 1 simple task. Why use many word when few do trick? Will likely remove other functions and perhaps create functions out of other blocks. I keep the logger script in a central share and make a local copy if it has changed, or load it from the central location if needed.

First I import the logger:

#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"

Define the log file:

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

What I log depends on debug levels that I created:

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

I would probably consider myself a bit of a "hack" when it comes to coding so this might not be the prettiest but here is my version of logger.ps1:

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

    [Parameter(Mandatory=$false)]
        [int64]$logSize = 10mb,
    [Parameter(Mandatory=$false)]
        [int]$logCount = 25
) 
# end of settings

function Write-Log-Line ($line, $logFile) {
    $logFile | %{ 
           If (Test-Path -Path $_) { Get-Item $_ } 
           Else { New-Item -Path $_ -Force } 
    } | Add-Content -Value $Line -erroraction SilentlyCOntinue
}

您可能只想使用新的 TUN.Logging PowerShell 模块,这也可以发送日志邮件。只需使用 Start-Log 和/或 Start-MailLog cmdlet 开始日志记录,然后使用 Write-HostLog、Write-WarningLog、Write-VerboseLog、Write-ErrorLog 等写入控制台和日志文件/邮件。然后在最后调用 Send-Log 和/或 Stop-Log ,瞧,您就得到了日志记录。
只需从 PowerShell Gallery 安装它

Install-Module -Name TUN.Logging

,或者只需点击链接: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

You might just want to use the new TUN.Logging PowerShell module, this can also send a log mail. Just use the Start-Log and/or Start-MailLog cmdlets to start logging and then just use Write-HostLog, Write-WarningLog, Write-VerboseLog, Write-ErrorLog etc. to write to console and log file/mail. Then call Send-Log and/or Stop-Log at the end and voila, you got your logging.
Just install it from the PowerShell Gallery via

Install-Module -Name TUN.Logging

Or just follow the link: https://www.powershellgallery.com/packages/TUN.Logging

Documentation of the module can be found here: https://github.com/echalone/TUN/blob/master/PowerShell/Modules/TUN.Logging/TUN.Logging.md
