由于監(jiān)控及報告需要，要統(tǒng)計性能計數(shù)器每天數(shù)值情況，確認數(shù)據(jù)庫服務器的運行狀況。若打開計數(shù)器填寫，比較麻煩，現(xiàn)在統(tǒng)計用 powershell 來讀取計數(shù)器的值。

第一階段：Powershell 讀取計數(shù)器文件并統(tǒng)計其中一個計數(shù)器的值

$startDate = (Get-Date).AddDays(-1).Date $endDate = (Get-Date).Date $perfPath = "D:/DataFiles/PERFMON/MSSQL_PERFMON_08240904.blg"  #讀取文件中的計數(shù)器名稱 $counterList = Import-Counter -Path $perfPath $countersNameList = $counterList[0].countersamples | % {$_.path}  #篩選指定計數(shù)器和時間重新導入PS $counter = $countersNameList -like '*Processor Time*' $counterData = Import-Counter -Path $perfPath -Counter $counter | Where-Object -FilterScript {($_.Timestamp -ge $startDate) -and ($_.Timestamp -lt $endDate)}   #計算日期范圍內(nèi)的數(shù)值統(tǒng)計 $counterInfo = $counterData | Foreach-Object {$_.CounterSamples} | Measure-Object -property CookedValue -Average -Maximum  #哈希表存儲結果數(shù)據(jù) $resultTable=@{} $resultTable."CPU 利用率――平均" = $counterInfo.Average $resultTable."CPU 利用率――最大" = $counterInfo.Maximum  $resultTable

第二階段：批量統(tǒng)計文件中的所有計數(shù)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(shù)據(jù)  $resultTable=@{}  #導入指定時間的所有計數(shù)器信息 $counterData = Import-Counter -Path $perfPath | Where-Object -FilterScript {($_.Timestamp -ge $startDate) -and ($_.Timestamp -lt $endDate)}  #所有的計數(shù)器名字 $countersNameList = $counterData[0].countersamples | % {$_.Path}  #遍歷每個計數(shù)器，將計算結果存儲到哈希表中 foreach($counterName in $countersNameList)  {  #$counterName = "http://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 $resultTable.GetEnumerator() | sort Name | Format-List | Export-Csv -Path "D:/360Downloads/PerfmonCounter.xlsx" -Encoding "unicode" -Force
