Powershell小技巧之通过EventLog查看近期电脑开机和关机时间

2020-06-18 10:16脚本之家 PowerShell

本文主要讲诉了使用PowerShell如何得出电脑的开机、关机、在线时间等等信息，非常有帮助，有需要的朋友参考下

机器开机和关机时写在EventLog中的第一条日志和最后一条日志分别为：6005和6006。

									TimeCreated           Id LevelDisplayName Message

									-----------           -- ---------------- -------

									8/18/2014 9:23:04 AM     6005 Information   The Event log service was started.  

									8/15/2014 7:03:48 PM     6006 Information   The Event log service was stopped.

所以根据上面的信息很容易得出机器的开机，关机，在线时间，代码为：

									Function Get-ComputerUptimeHistory { 

									 $q=' 

									<QueryList> 

									 <Query Id="0" Path="System"> 

									  <Select Path="System">*[System[(EventID=6005 or EventID=6006)]]</Select> 

									 </Query> 

									</QueryList>'

									$events = Get-WinEvent -FilterXml $q

									$i=-1 

									while ( $i+1 -lt $events.length ) { 

									 if($i -eq -1) 

									 { 

									 [PSCustomObject]@{ 

									 StartTime = $events[0].TimeCreated; 

									 StopTime = $null ; 

									 UpTime = [datetime]::Now - $events[0].TimeCreated 

									 } 

									 } 

									 else{ 

									 [PSCustomObject]@{ 

									 StartTime = $events[$i+1].TimeCreated; 

									 StopTime = $events[$i].TimeCreated ; 

									 UpTime = $events[$i].TimeCreated - $events[$i+1].TimeCreated 

									 } 

									 } 

									 $i += 2 

									} 

									}

输出为：

									PS> Get-ComputerUptimeHistory | ft -AutoSize

									StartTime       StopTime       UpTime

									---------       --------       ------
