Powershell腳本來監控DFSR積壓

沒問題。只是分享。道歉，如果這是錯誤的場地和/或方法，但我已經從這些論壇採取了很多，只是想稍微回過頭來，以防其他人喜歡試圖學習PS並在PS中做一些基本上有用的事情。道歉，但我必須通過編輯器運行腳本。反正這裏是：Powershell腳本來監控DFSR積壓

腳本的功能是...對於五個不同的DFSR羣集對和五個不同的DFSR命名空間，請檢查DFSR（即複製）是否已啓用/開啓/已啓動/已配置，如果是，則查詢兩端DFSR關係並顯示積壓計數器。我已經使用了一個函數來減少顯示/報告/列表/屏幕/顯示更新率，即我對積壓計數的微小變化不感興趣，但我確實想跟蹤基本活動和大量積壓事件，即檢測DFSR實際上在工作。 HTH。 – sdo

如果你想展示你寫的代碼，請使用博客或論壇。如果您必須將其發佈在SO上：如果您發佈有關您的腳本解決的問題的問題，然後將您的腳本（包括一些解釋）作爲自己的答案發布，但只是將代碼發佈爲（非 - ）問題顯然是題外話題。 –

好 - 理解 - 不會再發生。 – sdo

這不是一個真正的「具體問題」，所以我要表現得好像這是CodeReview.StackExchange代替。

$count = fn_count($count) - 功能在PowerShell中調用不使用() - 除非你想傳遞數組作爲參數 - 他們只是像的cmdlet。 $count = fn_count $count
fn_is_numeric($p1) - 使用[int]::TryParse()或轉換爲[int]並捕獲錯誤。
fn_count($p1) - 有問題的Visual Basic樣式冗餘命名樣式，舊樣式參數聲明，無用參數名稱
fn_count - 什麼。該函數在11行中包含字詞return 14次。它會轉換爲字符串，你也可以在通話時進行操作，並且它可以完成將最後兩位數字壓縮到00或者說< 100或0的所有內容。而且它有錯誤 - 將170放入並且它會顯示200 +。
[System.IO.Path]::GetDirectoryName()和朋友 - >複製粘貼代碼[IO.FileInfo]和.Directory
羣衆 - > 5號線的設置和一個ForEach環
使用Hashtable中的重複數據，而不是許多單獨命名變量
$("{0:F0}" -f $z_lines).PadLeft(5)出現的要做"$z_lines".PadLeft(5)
DFSRDiag調用您有10行復制粘貼和5個自定義變量名稱只是爲了將文本'OK'或'UNKNOWN'帶到腳本的下一部分。與下面的複製麪食混合在一起。他們已經很臃腫，但可以因爲清理...

此：

if ($?) {$count = [string]$set.Count} else {$count = "ERROR"} 
if ($count -ne "ERROR") { 
    if ($count -ne "100") { $count = fn_count($count) } else { 
    $verbose = [string]$verbose ; $count = $verbose.Split(" ")[-1] ; $count = fn_count($count) } } 
$AppAxx_Display = $count

這樣做的「我的複製粘貼代碼需要很長的感覺，我要去通過REALLYCRAMMINGEVERYTHINGUPUNREADABLY縮短它; fn_count已經將$ p1轉換爲字符串，所以在這裏跳過這樣做，fn_count直接傳遞非數字字符串，因此您可以跳過檢查它是否爲「ERROR」並僅通過它提供它。（它怎麼可能不是已經？），忘記很多嵌套難以閱讀的嵌套if/else，忘記存儲$計數實際上 - 將一個或其他東西放入fn_count並一次性將結果分配給AppAxx。

的$表/格式表shennanigans：IDK的，但與5號線的設置代碼的foreach循環我認爲它可以大都被壓扁。
此$Verbose = $($set = $(Get-DFSRBackLog ... | Select FullPathname)) 4>&1未註釋伏都教。我甚至不想去碰它。

不管怎樣，我放棄fn_is_numeric，設置五個服務器及其複製件的Hashtable和轉向的兩大塊複製粘貼到一個循環，掏出雙GET-DFSRBacklog呼叫到一個函數並將fn_count合併到其中，將"0,0"測試移至源代碼中，通過重新使用前面設置的相同哈希表修改$table的內容，刪除了一堆()，奇怪的數字格式，雙線可能是一個，並且通常敲100多行關閉它，並修復了170-> 200+錯誤：

令人驚歎！非常感謝您抽出時間仔細分析我糟糕的代碼。哦，是的，你的結果在概念上是合理的。一個noob的第一個劇本與真正應該如何完成的區別是一個很好的例子。多麼美妙的學習練習。 – sdo

我唯一需要做的事情是：i）在調用DFSRdiag時封裝'$ _。Name'（和其他）實體，即我必須使用'/switch:$($_.Name）'，並且ii ）對於你來說不是很明顯，有時返回的count是一個空字符串「」，所以我添加了兩個if語句將「」更改爲「0」。除了這兩點，這是一個完美的重寫。我會再說一遍，比你非常清楚的一課。非常感謝。 – sdo

re ii ii）實際上在主函數中，Get-DSFRBackLog的返回結果有時是$ Null，所以測試一下，並將$ Count改爲零。 – sdo
