#讀取文件中的計數器名稱 
$counterList = Import-Counter -Path $perfPath

第二階段：批量統(tǒng)計文件中的所有計數器并導出到文件中

$startDate = (Get-Date).AddDays(-1).Date  
$endDate = (Get-Date).Date  
$perfPath = "D:\360Downloads\*.blg" 
 
#哈希表存儲結果數據  
$resultTable=@{} 
 
#導入指定時間的所有計數器信息 
$counterData = Import-Counter -Path $perfPath | Where-Object -FilterScript {($_.Timestamp -ge $startDate) -and ($_.Timestamp -lt $endDate)} 
 
#所有的計數器名字 
$countersNameList = $counterData[0].countersamples | % {$_.Path} 
 
#遍歷每個計數器，將計算結果存儲到哈希表中 
foreach($counterName in $countersNameList)  
{  
#$counterName = "\\hzc\system\threads" 
$counterDataOne = $counterData | Foreach-Object {$_.CounterSamples} | Where {$_.Path -like $counterName}  
$counterInfo = $counterDataOne | Measure-Object CookedValue -Average -Minimum -Maximum 
$resultTable.$($counterName+" ：平均值") = $counterInfo.Average 
$resultTable.$($counterName+" ：最小值") = $counterInfo.Minimum 
$resultTable.$($counterName+" ：最大值") = $counterInfo.Maximum 
} 
 
#$resultTable.GetEnumerator() | sort Name | Format-Table -Auto 
#幾種方法導出到文件 
$resultTable.GetEnumerator() | sort Name | Format-Table -Auto | Out-File "D:\360Downloads\PerfmonCounter.txt" 
$resultTable.GetEnumerator() | sort Name | Export-Csv -Path "D:\360Downloads\PerfmonCounter.txt" -Encoding "unicode" -Force
