Question

我正在尝试设置一个脚本来监控来自500个错误的IIS 7.5日志。现在我可以做到这一点，但我希望每30分钟检查一次。很自然地，我不想让它警告我已经报道过的500个错误。

从下面的脚本中我可以看到，我添加了一个$ time变量来考虑这一点，但是我似乎找不到使用这个变量的方法。任何帮助将不胜感激。

#Set Time Variable -30
$time = (Get-Date -Format hh:mm:ss (Get-Date).addminutes(-30))
# Location of IIS LogFile
$File = "C:\Users\here\Documents\IIS-log\"+"u_ex"+(get-date).ToString("yyMMdd")+".log"
# Get-Content gets the file, pipe to Where-Object and skip the first 3 lines.
$Log = Get-Content $File | where {$_ -notLike "#[D,S-V]*" }
# Replace unwanted text in the line containing the columns.
$Columns = (($Log[0].TrimEnd()) -replace "#Fields: ", "" -replace "-","" -replace "\(","" -replace "\)","").Split(" ")
# Count available Columns, used later
$Count = $Columns.Length
# Strip out the other rows that contain the header (happens on iisreset)
$Rows = $Log | where {$_ -like "*500 0 0*"}
# Create an instance of a System.Data.DataTable
#Set-Variable -Name IISLog -Scope Global
$IISLog = New-Object System.Data.DataTable "IISLog"
# Loop through each Column, create a new column through Data.DataColumn and add it to the DataTable
foreach ($Column in $Columns) {
  $NewColumn = New-Object System.Data.DataColumn $Column, ([string])
  $IISLog.Columns.Add($NewColumn)
}
# Loop Through each Row and add the Rows.
foreach ($Row in $Rows) {
 $Row = $Row.Split(" ")
 $AddRow = $IISLog.newrow()
 for($i=0;$i -lt $Count; $i++) {
 $ColumnName = $Columns[$i]
 $AddRow.$ColumnName = $Row[$i]
}
 $IISLog.Rows.Add($AddRow)
 }
 $IISLog | select time,csuristem,scstatus

确定在KevinD的帮助下和PowerGUI进行了一些试验和错误，我得到了它的预期工作。这是成品。

#Set Time Variable -30
$time = (Get-Date -Format "HH:mm:ss"(Get-Date).addminutes(-30))
# Location of IIS LogFile
$File = "C:\Users\here\Documents\IIS-log\"+"u_ex"+(get-date).ToString("yyMMdd")+".log"
# Get-Content gets the file, pipe to Where-Object and skip the first 3 lines.
$Log = Get-Content $File | where {$_ -notLike "#[D,S-V]*" }
# Replace unwanted text in the line containing the columns.
$Columns = (($Log[0].TrimEnd()) -replace "#Fields: ", "" -replace "-","" -replace "\(","" -replace "\)","").Split(" ")
# Count available Columns, used later
$Count = $Columns.Length
# Strip out the other rows that contain the header (happens on iisreset)
$Rows = $Log | where {$_ -like "*500 0 0*"}
# Create an instance of a System.Data.DataTable
#Set-Variable -Name IISLog -Scope Global
$IISLog = New-Object System.Data.DataTable "IISLog"
# Loop through each Column, create a new column through Data.DataColumn and add it to the DataTable
foreach ($Column in $Columns) {
  $NewColumn = New-Object System.Data.DataColumn $Column, ([string])
  $IISLog.Columns.Add($NewColumn)
}
# Loop Through each Row and add the Rows.
foreach ($Row in $Rows) {
  $Row = $Row.Split(" ")
  $AddRow = $IISLog.newrow()
  for($i=0;$i -lt $Count; $i++) {
    $ColumnName = $Columns[$i]
    $AddRow.$ColumnName = $Row[$i]
  }
  $IISLog.Rows.Add($AddRow)
  }
  $IISLog | select @{n="Time"; e={Get-Date -Format "HH:mm:ss"("$($_.time)")}},csuristem,scstatus | ? { $_.time -ge $time }

再次感谢Kev，你是一个好人。希望这段代码可以帮助其他人。

尝试将最后一行更改为：

$IISLog | select @{n="DateTime"; e={Get-Date ("$($_.date) $($_.time)")}},csuristem,scstatus | ? { $_.DateTime -ge $time }

在select中，我们将日期和时间字段连接起来，然后将它们转换为日期对象，然后选择此字段大于$ time变量的行。

您还需要更改$ time变量：

$time = (Get-Date).AddMinutes(-30)

你想要一个DateTime对象，而不是字符串。
