There is no such alerting rule that would monitor the processes and alert if a specific process is shut down. We have rules similar to this but specifically for our agent services.
I think that would be a great idea and would suggest raising an enhancement request here: https://ivanticore.uservoice.com/forums/904675-endpoint-manager
Otherwise, you can enable Real-Time Inventory and Monitoring for that agent and occasionally check if the service is running from the console. This will require an agent reinstall. Here is more information on that:
After you have the Real-Time agent installed, you can view the agents processes and services by right clicking the device and choosing "Inspect".
I hope this helps.
