Setup Alert when SQL Agent Down using Task Scheduler - sql

Question

I am looking something to setup alert notification when SQL agent is down, sometimes when windows patch apply or server get rebooted SQL Agent is not restarting even though we have set up SQL Agent properties Auto Restart SQL Server if it stops unexpectedly
Auto Restart SQL Server Agent if it stops unexpectedly.
I have also tried to setup services on Component service on server to at Recovery tab, First Failure Restart the service and also restarted service rebooted but didn't work.
Is it any way I can get the alert so I can restart service manually when it's Agent is down it it will trigger to restart the job when Agent it's down.

$AgentStatus = (Get-Service -ComputerName <CompName> -Name <SqlServerAgentName> | Where-Object {$_.Status -eq "Stopped"} | Measure-Object).Count
If($AgentStatus -eq 1){
Start-Service -Name SqlServerAgentName
$SMPTPort = <Specify port number>
$From = "email1#domain.com"
$To = "email2#domain.com"
$Subject = "The SQL Server Agent Service in $env:ComputerName has been restarted."
$Body = "The SQL Server Agent Service <SqlServerAgentName> was in a Stopped state and has been restarted."
$SMTPServer = "SMTP SERVER"
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, $SMPTPort)
$SMTPClient.EnableSsl = $false
$SMTPClient.Send($From, $To, $Subject, $Body)}

You can try creating a batch file below which checks for service status. This sends an SMTP mail (using powershell) along with restarting service again.
for /F "tokens=3 delims=: " %%H in ('sc query "MyServiceName" ^| findstr " STATE"') do (
if /I "%%H" NEQ "RUNNING" (
powershell -ExecutionPolicy ByPass -Command Send-MailMessage -SmtpServer SMTPSERVER -To someone#domain.com -From noreply#domain.com -Subject Testing -Body Service_Not_Running
net start "MyServiceName"
)
)
Once you have the script ready, create a task scheduler to call the batch file. Run the scheduler every 1 hr or so.
