Monitoring Microsoft Exchange Server 2010, 2013 and 2016 services with PowerShell script and task scheduler

Most enterprise environments have solutions that provide monitoring services to ensure Microsoft Exchange Server services are running and if they are not, restart the service and send an email notification to administrators but I have constantly come across smaller business that may not be able to afford such applications and therefore have implemented scripts with task manager scheduled tasks to provide some form of service monitoring. The Exchange Health Check Report by Paul Cunningham (https://practical365.com/exchange-server/powershell-script-exchange-server-health-check-report/) is great for daily reports but it is not practical to constantly use it for monitoring so what I’ve typically used is implement the service_check.ps1 script written by Kevin Olson:

Check for hung or stopped services
https://gallery.technet.microsoft.com/scriptcenter/Check-for-hung-or-stopped-67bc718d

The small adjustment I’ve made to the script is to move the Send-Mailmessage cmdlet to execute after the Start-Service because if you do not have another SMTP relay setup and need to rely on the Exchange server this script is monitoring, the email will not be sent out if the service that is hung or stopped is the transport service. The following are the scripts along with the Exchange services added into the script for each version:

    foreach ($srv in $ServiceArray)

    {

        if ($Service.name -eq $srv)

            #check if a service is hung

            if ($Service.status -eq "StopPending")

            {

            $servicePID = (gwmi win32_Service | where { $_.Name -eq $srv}).ProcessID

            Stop-Process $ServicePID

            Start-Service -InputObject (get-Service -ComputerName $Computer -Name $srv)

            #email to notify if a service is down

            Send-Mailmessage -to administrator@someDomain.com -Subject "$srv is hung on $Computer" -from exchange@contoso.com -Body "The $srv service was found hung." -SmtpServer localhost

            }

            # check if a service is stopped

            elseif ($Service.status -eq "Stopped")

            {

            #automatically restart the service.

            Start-Service -InputObject (get-Service -ComputerName $Computer -Name $srv)

                   #email to notify if a service is down

            Send-Mailmessage -to administrator@someDomain.com -Subject "$srv is stopped on $Computer" -from exchange@contoso.com -Body "The $srv service was found stopped." -SmtpServer localhost

            }

        }

    }

}

The services I included in the script are all of the ones listed as Automatic as well as Automatic (Delayed Start):

World Wide Web Publish Service is also included.

Task Scheduler Configuration

One of the methods to execute the script repeatedly on the server is to create a task in the Task Scheduler as such:

image

Create a trigger and specify a Repeat task every however frequently you like:

Then create an action with powershell.exe as the Program/script and the following as the Add arguments (optional) field:

-command "& 'C:\Scripts\service_check.ps1'"

image

Extra Setup Information

This script can be used for other services as well and an easy way of obtaining the service names to monitor is use cmdlets such as the one below to list all the services that contains, say, Microsoft Exchange:

Get-Service | Where {$_.DisplayName -like "Microsoft Exchange*"} | format-table -autosize

checking on service statuses is not perfectly a reliable way. Best is use powershell to check on the status of a web page in this case OWA and if the script is getting 404 error code then it restarts the services if not then it does not. or check on 200 which means the owa page is up and user is able to login to their mailbox
