如何监视日志文件并在它停止时发送警报？

Question

有没有办法监视日志文件并在文件停止写入新行时发送警报（电子邮件）？

Answer 1

您可以使用来自 .NET 的计时器实例，例如 Timer from .NET and on the timer handler check the last modified date of your file. You can get the last modified date of a file using System.IO.File.GetLastWriteTime。如果上次修改日期足够早，那么您可以发送警报。

Answer 2

下面是实现所需结果的 powershell 脚本。执行脚本后代码将每五分钟执行一次，除非 powershell window 关闭，无需在任务调度程序中安排脚本。

$LogFile = "C:\logs\mylogFile.log"
while($true)
{
    $LastWriteTime = (Get-ChildITem $LogFile).LastWriteTime
    $CurrentTime = Get-Date
    $Diff = (New-TimeSpan -Start $LastWriteTime -End $CurrentTime).TotalMinutes
    If($Diff -gt 5)
    {
        #Send Email Alert if file not written from last 5 minutes or Alert That you want
    }

    sleep -Seconds (60*5)
}
