Powershell小技巧之从文件获取系统日志

有时你可能会需要分析系统文件将他们传输到硬盘，或你想直接从“evtx”读取系统日志。

你可以这样做：

$path = "$env:windir\System32\Winevt\Logs\Setup.evtx"

Get-WinEvent -Path $path

另附上一段获取系统日志的代码

$StartTime = (get-date).Date + (new-timespan -Hours 6 -Minutes 35)

$EndTime = (get-date).Date + (new-timespan -Hours 6 -Minutes 36)

$global:TaskStart

$Global:TaskComplete

$Global:events

$Global:event

$Global:TimeSpent

$Global:events = get-winevent -FilterHashtable @{logname = "Microsoft-Windows-TaskScheduler/Operational"; ID=107;StartTime=$StartTime;EndTime=$EndTime}

Foreach($Global:event in $Global:events)

{

    cls

    $StartLogs=get-winevent -FilterHashtable @{logname = "Microsoft-Windows-TaskScheduler/Operational";ID=100;StartTime=$StartTime}

    $CompleteLogs=get-winevent -FilterHashtable @{logname = "Microsoft-Windows-TaskScheduler/Operational";id=102;StartTime=$StartTime}

    $global:TaskStart=$StartLogs | where {$_.ActivityId -eq $Global:event.ActivityId}

    $Global:TaskComplete=$CompleteLogs | where {$_.ActivityId -eq $Global:event.ActivityId}

    $global:TimeSpent=($global:TaskComplete.timeCreated-$global:TaskStart.timeCreated).TotaLMinutes

    if(($global:TaskStart -ne $NULL) -and ($Global:TaskComplete -ne $null) -and ($Global:TimeSpent -gt 1)){

           

        $Messagebody="Sync task started at:  "+$global:TaskStart.TimeCreated.DateTime+"`r`n"

        $Messagebody=$Messagebody+"`r`nSync task completed at:  "+$global:TaskComplete.timeCreated.DateTime+"`r`n"

        $Messagebody=$Messagebody+"`r`nTask lasted for "+("{0:N2}" -f ($Global:TimeSpent) )+" minutes"

           

        Send-MailMessage -From "CustomerLog@avepoint.com" -To "Zhijie.bai@avepoint.com","Infrastructure_cn@avepoint.com" -Subject "Customer Logs Sync Report:Success" -Body $Messagebody -SmtpServer "10.100.100.153" -Encoding UTF8

    }

    else{

        $Messagebody="########################################################################`r`n"

        $Messagebody=$Messagebody+"`r`nCustom logs Sync failed, please login 10.2.0.125 to check and sync again`r`n"

        $Messagebody=$Messagebody+"`r`n########################################################################`r`n"

        Send-MailMessage -From "CustomerLog@avepoint.com" -To "Zhijie.bai@avepoint.com","Infrastructure_cn@avepoint.com" -Subject "Customer Logs Sync Report:Failed" -Body $Messagebody -SmtpServer "10.100.100.153" -Encoding UTF8 -Priority High

    }

}
