   I have got a question regarding the reliability script:
   From my understanding, the higher the SystemStabilityIndex the better. In your script you check wether the current index is greater than our threshold for throwing an error though, which would imply the lower the better. Am I understanding the index wrong?

      Ben, you’re right! I’ll fix it in the blog right now. I changed it during my testing and never flipped it back. Thanks for letting me know!

         Thanks for making that clear. I would also suggest then to change the Write-Host to “The system stability index is lower than expected.” or something along those lines. Otherwise thanks for the great script!

   Hi Kelvin,

   I tried the Windows Reliability script, but nothing happens. Do you have any clue what is going on?
   I am running it in Powershell ISE. No errors or write-hosts are appearing.

   Kind regards,

   Remco

   Hey Kelvin,

   Long time follower of your stuff and first off thanks for all your hard work and contributions. I’m using this to identify our EOL devices and just ran it but it only returns 1 device although I show a lot more of devices labeled EOL. Not sure if I’m doing something wrong or not?

   Hey Kelvin,

   I was able to resolve this by just making a list of devices on the EOL list and then making a new filter.

   $EOLDevices = ‘U2S48′,’BZ2′,’U2O’,’U2HSR’,’U2Sv2′,’U7P’,’U2L48′,’U2Lv2′,’U7P’,’U7IWP’,’U7EDU’,’U2IW’
   $AllDevices = foreach ($site in $sites) {
   $Devices = (Invoke-RestMethod -Uri “$UnifiBaseUri/s/$($site.name)/stat/device” -WebSession $websession).data
   $Devices | Select-Object _id, name, ip, mac, model, type, version, unsupported,@{label = ‘site’; expression = { $site.desc }},@{label = ‘EOL’; expression = { $EOLDevices -contains $_.model}}
   }

   $AllDevices | Where-Object {$_.EOL -eq $true} | Out-GridView

   How did you get powershell to accept the self signed certificate?
