How to add fault tolerance?

PowerShell Help
1

Good morning!

I’ve compiled some scripts that I’ve had some help with to stop a service, make sure it’s stopped before starting the service back up, I think I have that part working. What I would like to add is if the service never comes back up after 3 try’s at 5 min a piece (300 sec)that it will give up and email out that the service restart has failed so we can manually intervene.

Any help would greatly be appreciated. I’m a novice at best.

$ServiceName = ‘Adobe Acrobat Update Service’
$arrService = Get-Service -Name $ServiceName
while ($arrService.Status -eq ‘Running’)
{
Stop-Service -Name $ServiceName
write-host $arrService.Status
write-host ‘Service Stopping’
start-sleep -seconds 10
$arrService.Refresh()
if ($arrService.Status -ne ‘Running’)
{
Write-Host ‘Service is now Stopped’
}
}
while ($arrService.Status -ne ‘Running’)
{

Start-Service $ServiceName
write-host $arrService.status
write-host 'Service starting'
Start-Sleep -seconds 10
$arrService.Refresh()
if ($arrService.Status -eq 'Running')
{
    Write-Host 'Service is now Running'
}

}
$arrService.Refresh()
$Subject = ($arrService.Status)

$body = Restart-MyService | Out-String

$email = @{
From = “@email.com”
To = “@email.com”
Subject = $Subject
SMTPServer = “smtp.******.com”
Body = $body
}

send-mailmessage @email

It’d help immensely if you could format your code, as indicated in the bullet points above the posting text box. It’s difficult to follow the logic as-is.

$ServiceName = 'Adobe Acrobat Update Service'
$arrService = Get-Service -Name $ServiceName
while ($arrService.Status -eq 'Running')
{
Stop-Service -Name $ServiceName
write-host $arrService.Status
write-host 'Service Stopping'
start-sleep -seconds 10
$arrService.Refresh()
if ($arrService.Status -ne 'Running')
{
        Write-Host 'Service is now Stopped'
    }
    }
while ($arrService.Status -ne 'Running')
{

    Start-Service $ServiceName
    write-host $arrService.status
    write-host 'Service starting'
    Start-Sleep -seconds 10
    $arrService.Refresh()
    if ($arrService.Status -eq 'Running')
    {
        Write-Host 'Service is now Running'
    }

}
$arrService.Refresh()
$Subject = ($arrService.Status) 

$body = Restart-MyService | Out-String

$email = @{
From = "emai.com"
To = "emai.com"
Subject =  $Subject
SMTPServer = "smtp.*******.com"
Body = $body
}

send-mailmessage @email

Sorry about that, I should of read.

I’m not 100% sure if I understood the goal but could it go like this

$ServiceName = 'Adobe Acrobat Update Service'
$i=0

do
{
    Stop-Service -Name $ServiceName
    sleep 10
    $status = (Get-Service -Name $ServiceName).Status

} while ($Status -eq 'Running')

Write-output 'Service is now Stopped'


do
{
    start-Service -Name $ServiceName
    sleep 300
    $i++
    $status = (Get-Service -Name $ServiceName).Status

} while (
        $status -eq 'Stopped' -or $i -ge 3
        )

if ($status -eq 'Running') {
                    Write-output 'Service is now Running'
                    }

Else {
    
    $body = @"
Hola,

Your service restart script failed to start $ServiceName

Please check the status

"@


    $email = @{
        From = "emai.com"
        To = "emai.com"
        Subject =  "[SuperFailure] $ServiceName did not start"
        SMTPServer = "smtp.*******.com"
        Body = $body
        }
    
    send-mailmessage @email
}

Thank you very much Aapeli!

It’s very close to what I want from what I can read, I’ll test it in a moment. The only other thing I Would need is for it to also email upon success.

Another example:

$ServiceName = 'Foxit Reader Service'
$service = Get-Service -Name $ServiceName
$timeout = 0

while (($service.Status -ne 'Running') -and ($timeout -le 60)) {
    $service.Refresh()
    start-sleep -seconds 10
    "{0} is {1}. Paused for {2} of 60 seconds." -f $ServiceName, $service.Status, $timeout
    $timeout += 10
}

if ( $service.Status -eq 'Running' ) {
    "{0} service is up and running and good to go" -f $ServiceName
}
else {
    "{0} service didn't start in the time specified" -f $ServiceName
}

$ServiceName = 'Adobe Acrobat Update Service'
$i=0

do
{
    Stop-Service -Name $ServiceName
    sleep 10
    $status = (Get-Service -Name $ServiceName).Status

} while ($Status -eq 'Running')


do
{
    start-Service -Name $ServiceName
    sleep 300
    $i++
    $status = (Get-Service -Name $ServiceName).Status

} while (
        $status -eq 'Stopped' -or $i -ge 3
        )

if ($status -eq 'running') {
        $output = "$ServiceName is now Running"
        }
  else  {
        $output = "$ServiceName did not start"
        }


    
$body = @"
Hola,

$output

$email = @{
    From = "emai.com"
    To = "emai.com"
    Subject =  "[SuperFailure] $ServiceName did not start"
    SMTPServer = "smtp.*******.com"
    Body = $body
    }
