从正在运行的进程检查发送带有 CSV 的电子邮件

【中文标题】从正在运行的进程检查发送带有 CSV 的电子邮件

【英文标题】：Sending email with CSV from a Running Process check

【发布时间】：2022-01-23 00:24:18

【问题描述】：

我正在尝试检查一个进程是否正在远程计算机上运行（最终将是大约 100 台计算机）。如果进程没有运行，我希望它把计算机名/IP 放入 CSV，然后通过电子邮件发送出去。如果该过程在所有机器上运行，我希望脚本根本不发送电子邮件。为此，我想先测试机器以检查它们是否在线（如果它们离线，我们要么遇到更大的问题，要么出于某种原因关闭，但这不是这个过程正在检查的内容。

目前我将在几台机器上使用记事本进程测试这个脚本，因为我可以在测试机器上相对快速地完成它。

我现在有点卡住，因为我不知道如何将流程检查的结果放入 CSV 然后通过电子邮件发送。在下面的代码 sn-p 中，它没有生成输出文件，而是留下了我正在测试的变量以及附件在发送邮件消息中的路径。任何建议都将不胜感激，我目前仍在学习 powershell，所以还不知道所有的技巧和技巧。

干杯

# Mail server Configuration
$MailServer = "mail.server.co.uk"
$MailFrom = [e-mail]"

# Mail Content Configuration
$MailTo = "[e-mail]"
$MailSubjectFail = "INS Process not running on $DAU"
$MailBodyFail = "The INS Process on the DAU $DAU is not running. Please manually start process on DAU $DAU"

# Process Info
$Process = "Notepad"
$ProcessIsRunning =  Get-Process $Process -ErrorAction SilentlyContinue 

#Results Info
$Exportto = "C:\Scripts\Content\INSChecker\Results.csv"

# Get DAU Information
foreach($line in (Get-Content C:\Scripts\Content\INSChecker\INSList.cfg))
   
    $line = $line.split(",")

    $DAU = $line[0]
    $DAUIP = $line[1]

# Test Connection to INS DAU
write-host "Testing: $DAU / $DAUIP"
    $TestDAU = Test-Connection $DAU -quiet
    $TestDAUIP = Test-Connection $DAUIP -quiet

    write-host "Tests: $TestDAU / $TestDAUIP"
    
    If($TestDAU -ne 'True')
        If($TestDAUIP -ne 'True')
            write-host "DNS Not resolved for $DAU"

【参考方案1】：

希望这能给你一个关于从哪里开始以及如何解决问题的提示，我已经删除了脚本中不相关的部分，只留下了我个人会遵循的逻辑。

$report 的结果应该是一个object[]（对象数组），应该很容易操作并且很容易导出为 CSV：

@($report).where( $_.SendMail ) | Export-Csv $exportTo -NoTypeInformation

剩下的任务（附加 CSV、发送电子邮件等）留给您自己研究和设计。

$ErrorActionPreference = 'Stop'

# Process Info
$Process = "Notepad"
$ProcessIsRunning = 
    param($computer, $process)
    
    # On Windows PowerShell -ComputerName is an option,
    # this was removed on PS Core
    try
    
        $null = Get-Process $process -ComputerName $computer
        # If process is running return 'Running'
        'Running'
    
    catch
    
        # else return 'Not Running'
        'Not Running'
        # send a Warning to the console to understand why did this
        # fail ( couldn't connect or the process is not running? )
        Write-Warning $_.Exception.Message
    


#Results Info
$ExportTo = "C:\Scripts\Content\INSChecker\Results.csv"
$exportProps = 'Server', 'IP', 'Ping', 'DNSResolution', 'Process', 'SendMail'

# Get DAU Information
$report = foreach($line in Get-Content path/to/file.txt)

    $status = [ordered]@ | Select-Object $exportProps

    $DAU, $DAUIP = $line = $line.split(",")
    $status.SendMail = $false
    $status.Server = $DAU
    $status.IP = $DAUIP

    # Test ICMP Echo Request and DNS Resolution
    $ping = Test-Connection $DAUIP -Quiet
    $dns = Test-Connection $DAU -Quiet

    $status.Ping = ('Failed', 'Success')[$ping]
    $status.DNSResolution = ('Failed', 'Success')[$dns]
    $status.Process = & $ProcessIsRunning -computer $DAUIP -process $Process
    if(-not $ping -or -not $dns -or $status.Process -eq 'Not Running')
    
        $status.SendMail = $true
    

    [pscustomobject]$status


@($report).where( $_.SendMail ) # => This is what should be mailed
