A very simple colour-coded datastore report via email can be done like below.
To run this this every 4 hours you could use the Windows Task Scheduler on the station where you run the script.
You could also place the script in a loop, and run it every 4 hours.
Not sure how you want to tackle the scheduling.
$body = Get-Datastore |
Select @{N='Datastore';E={
$script:p = [math]::Round(($_.CapacityGB - $_.FreeSpaceGB)/$_.CapacityGB*100,1)
if($p -lt 70){"#fg#$($_.Name)#fe#"}
elseif($p -lt 90){"#fy#$($_.Name)#fe#"}
else{"#fr#$($_.Name)#fe#"}}},
@{N='CapacityGB';E={[math]::Round($_.CapacityGB,1)}},
@{N='FreeSpaceGB';E={[math]::Round($_.FreeSpaceGB,1)}},
@{N='UsedPercent';E={$script:p}} | ConvertTo-Html
$body = $body.Replace('#fg#','<font color=green>').Replace('#fy#','<font color=yellow>').Replace('#fr#','<font color=red>').Replace('#fe#','</font>')
$sMail = @{
To = 'my.name@domain'
From = 'report@domain'
Subject = 'Datastore Report'
BodyAsHtml = $true
Body = $body | Out-String
