Good afternoon, I am trying to create a power shell script to give me a % of up time on production servers
I was able to run the script and it shows good output on the screen but sends nothing to e-mail.
It also seems it overwrites the $body with the last entry.
$body =#>
#$Diff = 86400000*$DaysAgo # Milliseconds in a day
$startDate = get-date $(get-date).AddMonths(-1).ToString("01/MM/yyyy")
$endDate = $startDate.AddMonths(1).AddMilliseconds(-1)
$XMLFilter = "<QueryList>
<Query Id=`"0`" Path=`"System`">
<Select Path=`"System`">*[System[( (EventID = 6005 or EventID = 6006) ) and TimeCreated[@SystemTime>='
$($startDate.tostring("yyyy-MM-dd"))T00:00:00.000Z' and @SystemTime<='$($endDate.tostring("yyyy-MM-dd"))T22:59:59.999Z']]]</Select>
</Query>
</QueryList>"

[string[]]$Computers = "SERVER1", "SERVER2", "SERVER3" | Sort-Object ComputerName

$RebootEvents = get-winevent -FilterXML $XMLFilter -computername $Computer -ErrorAction SilentlyContinue -ErrorVariable FailedComputer | sort-object -Descending -property TimeCreated
$down = $null
$up = $null

Foreach($rebootEvent in $RebootEvents) {

$down = $rebootEvent.TimeCreated
} #end if eventID
Else {
$up = $rebootEvent.TimeCreated
} #end else
if($down -AND $up) {
if($down -ge $up) {
Write-Host -foregroundColor Red "*** Invalid data. Ignoring $($up)"
$up = $down
}
#end if down is greater than up
[timespan]$CurrentDownTime = new-TimeSpan -start $down -end $up
$TotalDownTime += $currentDownTime
$down = $null
$up = $null
} #end if down and up
} #end foreach
$periodDifference = $endDate - $startdate
$minutesInMonth = $diff.mins
$minutesInDay = 24*60
$percentUpTime = (100 - ($TotalDownTime.TotalMinutes/$periodDifference.TotalMinutes)*100)
