Question

这是有效的..但是，它会给出以下错误消息：

Get-WmiObject : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty. Supply an argument that is not nul
l or empty and then try the command again.
At D:\WORK\ps\Tomcat1.ps1:116 char:67
+         $TomcatEvents=Get-WmiObject Win32_NTLogEvent -ComputerName <<<<  $servern -Filter "(Message like '%Tomcat%') AND (TimeWritten
 >= '$time')" |
    + CategoryInfo          : InvalidData: (:) [Get-WmiObject], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.PowerShell.Commands.GetWmiObjectCommand

我怀疑问题出在“服务器名称”列中，并注意到最后4行：

Server Name
SERVER (1.1.1.1) 
SERVER (1.1.1.1) 
SERVER (1.1.1.1) 
SERVER (1.1.1.1) 
() 
()

()

以下是代码：
