    Here is a simple PowerShell script that pings SITE_NAME. When scheduled to run with Task Scheduler, it will essentially just send regular "I'm alive" messages. You can of course extend it to do more things.

 Invoke-RestMethod PING_URL

    Save the above to e.g. C:\Scripts\healthchecks.ps1. Then use the following command in a Scheduled Task to run the script:

    -
    powershell.exe -ExecutionPolicy bypass -File C:\Scripts\healthchecks.ps1

    powershell.exe -ExecutionPolicy bypass -File C:\Scripts\healthchecks.ps1

    In simple cases, you can also pass the script to PowerShell directly, using the "-command" argument:
