ping、磁盘和服务检查

Question

我被要求拿出一个PowerShell脚本来做以下工作：

1. Ping服务器列表，如果ping不成功，则发送电子邮件
2. 如果ping成功，请检查磁盘空间以确保它有超过500 it的空闲空间。如果低于此阈值，请发送警报。
3. 若要检查IISADMIN和CCMEXEC服务是否正在运行，请再次发送警报。

我已经提出了下面的代码，但它似乎没有正确的工作，需要另一双眼睛来帮助我。

$rtn = $null
$Computer = $null
$EmailRecipient = "xxx@xxx.com","xxx@xxx.com"

# Lookup all computers from AD starting with XXXXX
$Computers = Get-ADComputer -Filter {name -Like "XXXXX*"} | select -ExpandProperty name

# Ping each computer
ForEach ($Computer in $Computers) {
    $rtn = Test-Connection -CN $computer.toUpper() -Count 1 -BufferSize 16 -Quiet

    IF ($rtn -match 'False') {
        # Send email to say computer unreachable
        #write-host $computer "unreachable"
        Send-MailMessage -From "ICT DESKTOP ALERTS<XXX@XXX.co.uk>" -To $EmailRecipient -Subject "DP Checker - Unreachable - $Computer" -Smtpserver emailrelay
    }
}

IF ($rtn -match 'True') {
    {
        foreach ( $computer in $computers ) {
            get-wmiobject Win32_LogicalDisk -computername $computer -ErrorAction SilentlyContinue | where-object { $_.FreeSpace -lt 500MB } | foreach-object {
                Send-MailMessage -From "xxx@xxx.com<xxx@xxx.com>" -To $EmailRecipient -Subject "DP Checker - Low HDD space - $Computer" -Smtpserver emailrelay
            }
        }
    }
    {
        IF ($IIS.State -ne 'Running') {
            Send-MailMessage -From "xxx@xxx.com<xxx@xxx.com>" -To $EmailRecipient -Subject "DP Checker - Service - IIS - Not Running - $Computer" -Smtpserver emailrelay
        }
    }
    {
        IF ($SMS.State -ne 'Running') {
            Send-MailMessage -From "xxx@xxx.com<xxx@xxx.com>" -To $EmailRecipient -Subject "DP Checker - Service - SMS - Not Running - $Computer" -Smtpserver emailrelay
        }
    }
}

# Check if IIS and SMS services are running
foreach ($computer in $computers) {
    $IIS = Get-WmiObject Win32_Service -Filter "Name = 'IISADMIN'" -ComputerName $computer -erroraction silentlycontinue
    $SMS = Get-WmiObject Win32_Service -Filter "Name = 'ccmexec'" -ComputerName $computer -erroraction silentlycontinue
}

您的脚本中的逻辑被破坏了。你先平所有的电脑。在此之后，只有当连接到上一台计算机的连接成功时，才在所有计算机上运行磁盘检查，并在尚未实际查询服务状态时尝试确定服务的状态。然后无条件地运行实际的服务检查(同样是在所有计算机上)。

将您的逻辑更改为如下所示：

ForEach ($computer in $computers) {
  $rtn = Test-Connection -CN $computer -Count 1 -BufferSize 16 -Quiet

  if (-not $rtn) {
    # ping failed
    Send-MailMessage ...
  } else {
    # ping succeeded
    Get-WmiObject Win32_LogicalDisk -Computer $computer |
      ? { $_.FreeSpace -lt 500MB } |
      % { Send-MailMessage ... }

    Get-WmiObject Win32_Service -Computer $computer -Filter "Name='IISADMIN'" |
      ? { $_.State -ne 'Running' } |
      % { Send-MailMessage ... }
    Get-WmiObject Win32_Service -Computer $computer -Filter "Name='ccmexec'" |
      ? { $_.State -ne 'Running' } |
      % { Send-MailMessage ... }
  }
}
