PowerShell 技能连载 - 获取睡眠或休眠的时间

适用于 PowerShell 所有版本

如果您希望确认某台机器是否频繁地进入睡眠或者休眠模式，以下是一个读取对应的日志并返回详细信息的函数。它能汇报计算机何时进入睡眠模式，以及它进入睡眠模式的时长：

function Get-HibernationTime
{

  # get hibernation events
  Get-EventLog -LogName system -InstanceId 1 -Source Microsoft-Windows-Power-TroubleShooter |
  ForEach-Object {
    # create new object for results
    $result = 'dummy' | Select-Object -Property ComputerName, SleepTime, WakeTime, Duration

    # store details in new object, convert datatype where appropriate
    [DateTime]$result.Sleeptime = $_.ReplacementStrings[0]
    [DateTime]$result.WakeTime = $_.ReplacementStrings[1]
    $time = $result.WakeTime - $result.SleepTime
    $result.Duration = ([int]($time.TotalHours * 100))/100
    $result.ComputerName = $_.MachineName

    # return result
    $result
  }
}
