New-Object System.IO.FileSystemWatcher多個服務器

Question

我有一個基於New-Object System.IO.FileSystemWatcher的腳本，用於監視我的主文件服務器上的文件夾以查找新文件，並運行外部應用程序，但現在我正在擴展New-Object System.IO.FileSystemWatcher的用法，以監視一組多個服務器（來自.csv的輸入）。

只要檢測到事件，我就得到了下面的代碼，但是當檢測到新文件時，它會多次爲新文件生成警報。任何想法我怎麼能得到它只是產生一個警報？我在想這就是我的循環結構？

任何幫助表示讚賞！

$Servers = import-csv "C:\Scripts\Servers.csv" 

while($true) { 

ForEach ($Item in $Servers) { 

# Unregister-Event $changed.Id -EA 0 
$Server = $($Item.Server) 
write-host "Checking \\$Server\c$\Scripts now" 

#$folder = "c\Scripts" 
$filter = "*.html" 

$watcher = New-Object System.IO.FileSystemWatcher 
$watcher.Path = "\\$Server\c$\Scripts\" 
$watcher.Filter = "*.html" 
$watcher.IncludeSubdirectories = $False 
$watcher.EnableRaisingEvents = $true 

     $created = Register-ObjectEvent $watcher "Created" -Action { 
     write-host "A new file has been created on $Server $($eventArgs.FullPath) -ForegroundColor Green 

    } 

} #ForEach 

write-host "Monitoring for new files. Sleeping for 5 seconds" 
Start-Sleep -s 5 

} #While 

這裏是我的腳本的單一服務器版本，基本上，我想要做同樣的事情，但對一羣服務器上運行：

$SleepTimer = 15 
$watcher = New-Object System.IO.FileSystemWatcher 
$watcher.Path = "\\FILESERVER\NEWSTUFF\" 
$watcher.Filter = "*.html" 
$watcher.IncludeSubdirectories = $true 
$watcher.EnableRaisingEvents = $true 

### DEFINE ACTIONS AFTER A EVENT IS DETECTED 
$action = { 
$path = $Event.SourceEventArgs.FullPath 
$changeType = $Event.SourceEventArgs.ChangeType 
$logline = "$changeType, $path" 
write-host "$LogLine created" 

**RUN EXTERNAL PROGRAM HERE** 

add-content -Value $LogLine -path "\\Fileserver\Log.txt" 

}  

### DECIDE WHICH EVENTS SHOULD BE WATCHED + SET CHECK FREQUENCY 
$created = Register-ObjectEvent $watcher "Created" -Action $action 

while ($true) { 
write-warning "no new files detected. Sleeping for $SleepTimer seconds ..." 
start-sleep -s $SleepTimer 
}

我覺得每個while循環時間執行時，新的文件系統觀察創建在產生。其中沒有腳本的您單個服務器版本發生的多個警報

你可以檢查此：

$Servers = import-csv "C:\Scripts\Servers.csv" 

ForEach ($Item in $Servers) { 

# Unregister-Event $changed.Id -EA 0 
$Server = $($Item.Server) 
write-host "Checking \\$Server\c$\Scripts now" 

#$folder = "c\Scripts" 
$filter = "*.html" 

$watcher = New-Object System.IO.FileSystemWatcher 
$watcher.Path = "\\$Server\c$\Scripts\" 
$watcher.Filter = "*.html" 
$watcher.IncludeSubdirectories = $False 
$watcher.EnableRaisingEvents = $true 

     $created = Register-ObjectEvent $watcher "Created" -Action {write-host "A new file has been created on $Server $($eventArgs.FullPath)" -ForegroundColor Green} 

} 


while($true) { 
write-host "Monitoring for new files. Sleeping for 5 seconds" 
Start-Sleep -s 5 

} #While
