App_Pool_Alert Powershell脚本

Question

我编写了一个power shell脚本，用于监视IIS应用程序池的状态。使用当前的方法，每当任何池下降时，它都会向我抛出一个警告，即池被停止，然后它再次启动池，发送电子邮件，声明池已关闭。因为我有大约50台服务器，所以大量邮件涌入，有时会导致垃圾邮件。有人能帮我在这里，以便脚本将扫描池目录，并将结果放在一个文本/html文件，并发送给我的列表，这些池在邮件中。请查找以下脚本：-

###################################Declear Servers in text file##############################################

$Servers = Get-Content C:\Users\Desktop\server.txt

################ Scans each server and import IIS web-administration module##################################

$Servers | ForEach-Object {
            Invoke-Command -ComputerName $_ -ScriptBlock {
            Import-Module WebAdministration
            cd IIS:/AppPools
            $CompName = (Get-WmiObject -Class Win32_ComputerSystem).Name
            $ApplicationPools = dir
foreach ($item in $ApplicationPools)
{
    $ApplicationPoolName = $item.Name
    $ApplicationPoolStatus = Get-WebAppPoolState $ApplicationPoolName
    If($ApplicationPoolStatus.value -eq "Stopped")

         {
            send-mailmessage -to "vvv@gmail.com" -from "xxx@gmail.com" -subject "Application Pool:- $ApplicationPoolName is Down on $CompName " -Body "$ApplicationPoolName is down. Please check IIS/Event logs for RCA." -SmtpServer ###########          

            Start-WebAppPool -Name $ApplicationPoolName

            send-mailmessage -to "vvv@gmail.com" -from "xxx@gmail.com" -subject "Application Pool:- $ApplicationPoolName is Up on $CompName " -Body "$ApplicationPoolName is Up and running fine." -SmtpServer #############         

          }

}

}}

以下是我重写脚本的方式：

###################################Declear Servers in text file##############################################

$Servers = Get-Content C:\server.txt

################ Scans each server and import IIS web-administration module##################################

$SMPTServer = "mail.server.com"
$result = "The following application pools were restarted:`n`n" # default output 

$Servers | ForEach-Object {
    $result += Invoke-Command -ComputerName $_ -ScriptBlock { # add output of scriptblock to $result
        Import-Module WebAdministration
        cd IIS:/AppPools
        $CompName = (Get-WmiObject -Class Win32_ComputerSystem).Name
        $ApplicationPools = dir
        foreach ($item in $ApplicationPools)
        {
            $ApplicationPoolName = $item.Name
            $ApplicationPoolStatus = Get-WebAppPoolState $ApplicationPoolName
            If($ApplicationPoolStatus.value -eq "Stopped")
                {    
                    Write-Output "Server $CompName - Application pool $ApplicationPoolName is Down - Restarting`n" # any action is added to otput
                    Start-WebAppPool -Name $ApplicationPoolName
                }
        }

    }
}
if ($result -ne "The following application pools were restarted:`n`n") { # If any action was taken send mail with $result
    send-mailmessage -to "vvv@gmail.com" -from "xxx@gmail.com" -subject "Application Pool Maitenance" -Body $result -SmtpServer $SMPTServer
}

首先定义一个$result变量，在本例中仅定义一个字符串。

使用scriptblock，您可以使用写输出将任何东西写入管道输出。此输出从返回并添加到$result变量中。

在脚本的末尾，检查$result变量是否已更改，并在需要时将其作为电子邮件正文发送。
