由于監(jiān)控及報(bào)告需要，要統(tǒng)計(jì)性能計(jì)數(shù)器每天數(shù)值情況，確認(rèn)數(shù)據(jù)庫服務(wù)器的運(yùn)行狀況。若打開計(jì)數(shù)器填寫，比較麻煩，現(xiàn)在統(tǒng)計(jì)用 powershell 來讀取計(jì)數(shù)器的值。
第一階段：Powershell 讀取計(jì)數(shù)器文件并統(tǒng)計(jì)其中一個計(jì)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(jì)數(shù)器名稱
$counterList = Import-Counter -Path $perfPath
$countersNameList = $counterList[0].countersamples | % {$_.path}
#篩選指定計(jì)數(shù)器和時(shí)間重新導(dǎo)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(jì)算日期范圍內(nèi)的數(shù)值統(tǒng)計(jì)
$counterInfo = $counterData | Foreach-Object {$_.CounterSamples} | Measure-Object -property CookedValue -Average -Maximum
#哈希表存儲結(jié)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(jì)文件中的所有計(jì)數(shù)器并導(dǎo)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(jié)果數(shù)據(jù)
$resultTable=@{}
#導(dǎo)入指定時(shí)間的所有計(jì)數(shù)器信息
$counterData = Import-Counter -Path $perfPath | Where-Object -FilterScript {($_.Timestamp -ge $startDate) -and ($_.Timestamp -lt $endDate)}
#所有的計(jì)數(shù)器名字
$countersNameList = $counterData[0].countersamples | % {$_.Path}
#遍歷每個計(jì)數(shù)器，將計(jì)算結(jié)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(dǎo)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
