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：

 

复制代码 代码如下:

$path = "$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

 

复制代码 代码如下:

$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 "[e-mail]" -To "[e-mail]","[e-mail]" -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 "[e-mail]" -To "[e-mail]","[e-mail]" -Subject "Customer Logs Sync Report:Failed" -Body $Messagebody -SmtpServer "10.100.100.153" -Encoding UTF8 -Priority High
    }
}
