Powershell脚本来监控DFSR积压
没问题。只是分享。道歉,如果这是错误的场地和/或方法,但我已经从这些论坛采取了很多,只是想稍微回过头来,以防其他人喜欢试图学习PS并在PS中做一些基本上有用的事情。道歉,但我必须通过编辑器运行脚本。反正这里是:Powershell脚本来监控DFSR积压

这不是一个真正的“具体问题”,所以我要表现得好像这是CodeReview.StackExchange代替。
-
$count = fn_count($count)
- 功能在PowerShell中调用不使用()
- 除非你想传递数组作为参数 - 他们只是像的cmdlet。$count = fn_count $count
-
fn_is_numeric($p1)
- 使用[int]::TryParse()
或转换为[int]并捕获错误。 -
fn_count($p1)
- 有问题的Visual Basic样式冗余命名样式,旧样式参数声明,无用参数名称 -
fn_count
- 什么。该函数在11行中包含字词return
14次。它会转换为字符串,你也可以在通话时进行操作,并且它可以完成将最后两位数字压缩到00或者说< 100或0的所有内容。而且它有错误 - 将170放入并且它会显示200 +。 -
[System.IO.Path]::GetDirectoryName()
和朋友 - >复制粘贴代码[IO.FileInfo]
和.Directory
- 群众 - > 5号线的设置和一个
ForEach
环 - 使用Hashtable中的重复数据,而不是许多单独命名变量
-
$("{0:F0}" -f $z_lines).PadLeft(5)
出现的要做"$z_lines".PadLeft(5)
-
DFSRDiag
调用您有10行复制粘贴和5个自定义变量名称只是为了将文本'OK'或'UNKNOWN'带到脚本的下一部分。与下面的复制面食混合在一起。他们已经很臃肿,但可以因为清理...
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 = $count
这样做的“我的复制粘贴代码需要很长的感觉,我要去通过REALLYCRAMMINGEVERYTHINGUPUNREADABLY缩短它; fn_count
已经将$ p1转换为字符串,所以在这里跳过这样做,fn_count
直接传递非数字字符串,因此您可以跳过检查它是否为“ERROR”并仅通过它提供它。 (它怎么可能不是已经?),忘记很多嵌套难以阅读的嵌套if/else
,忘记存储$计数实际上 - 将一个或其他东西放入fn_count并一次性将结果分配给AppAxx。
的$表/格式表shennanigans:IDK的,但与5号线的设置代码的foreach循环我认为它可以大都被压扁。
此
$Verbose = $($set = $(Get-DFSRBackLog ... | Select FullPathname)) 4>&1
未注释伏都教。我甚至不想去碰它。
不管怎样,我放弃fn_is_numeric
,设置五个服务器及其复制件的Hashtable和转向的两大块复制粘贴到一个循环,掏出双GET-DFSRBacklog呼叫到一个函数并将fn_count
合并到其中,将"0,0"
测试移至源代码中,通过重新使用前面设置的相同哈希表修改$table
的内容,删除了一堆()
,奇怪的数字格式,双线可能是一个,并且通常敲100多行关闭它,并修复了170-> 200+错误:

我没有做的是测试它,所以我怀疑它会按原样工作。不过,希望它在概念上是合理的。
令人惊叹!非常感谢您抽出时间仔细分析我糟糕的代码。哦,是的,你的结果在概念上是合理的。一个noob的第一个剧本与真正应该如何完成的区别是一个很好的例子。多么美妙的学习练习。 – sdo
我唯一需要做的事情是:i)在调用DFSRdiag时封装'$ _。Name'(和其他)实体,即我必须使用'/switch:$($_.Name)',并且ii )对于你来说不是很明显,有时返回的count是一个空字符串“”,所以我添加了两个if语句将“”更改为“0”。除了这两点,这是一个完美的重写。我会再说一遍,比你非常清楚的一课。非常感谢。 – sdo
re ii ii)实际上在主函数中,Get-DSFRBackLog的返回结果有时是$ Null,所以测试一下,并将$ Count改为零。 – sdo
脚本的功能是...对于五个不同的DFSR群集对和五个不同的DFSR命名空间,请检查DFSR(即复制)是否已启用/开启/已启动/已配置,如果是,则查询两端DFSR关系并显示积压计数器。我已经使用了一个函数来减少显示/报告/列表/屏幕/显示更新率,即我对积压计数的微小变化不感兴趣,但我确实想跟踪基本活动和大量积压事件,即检测DFSR实际上在工作。 HTH。 – sdo
如果你想展示你写的代码,请使用博客或论坛。如果您必须将其发布在SO上:如果您发布有关您的脚本解决的问题的问题,然后将您的脚本(包括一些解释)作为自己的答案发布,但只是将代码发布为(非 - )问题显然是题外话题。 –
好 - 理解 - 不会再发生。 – sdo
