使用PowerShell检查Tomcat服务器网页

标签： powershell tomcat smtp alert

下面有一份好的工作副本。我还修改了varibles而不是缩写。

但是，根据Good部分（在其他地方之外），如果存在内容问题，则希望内容也被检查三次。

如果存在Web异常，则会正确检查三（3）次。但是，如果服务器已启动并且正在运行，则不会检查内容是否重新检查它所查找的字符串：

为了清晰起见重写这个，就在之前：catch [Net.WebException]我确实尝试写了我正在寻找的部分，但无法让它工作。我可能在这方面不正确，因为[Net.WebException]可能会为此接受错误处理。

            else
            {
                #BAD CONTENT
                if ($Retrycount -gt 2){
                    if (!(Test-Path "$($mypath)\$servern$flag")) {
                        "$(get-date -Format 'hh:mm, dd/MM/yyyy') - $($string)" | Out-File "$($mypath)\$servern$flag"
                        Add-Content $fileName "<tr>"
                        Add-Content $fileName "<td align='center'> $servern ($ip) </td>"

                    $Stoploop = $true
                }
            Write-Host "$RetryCount $servern is not up and running retrying in 10 seconds..."
            Start-Sleep -Seconds 10
            $Retrycount = $Retrycount + 1
            }

    catch [Net.WebException] {

WebCheck_computers.txt包含：

SERVER01,10.10.10.10,80,http://10.10.10.10/
SERVER02,10.10.10.11,80,http://10.10.10.11/

现在，让我们展示当前的工作代码：
