SQL Server Windows Service

Microsoft.SQLServer.2016.DBEngine.ServiceMonitor (UnitMonitor)

This monitor checks the status of the SQL Server Database Engine service.

Knowledge Base article:

Summary

This monitor checks the state of the SQL Database Engine Windows Service.

Causes

"Not Running" state of this monitor indicates that SQL DB Engine service is configured to start automatically but is in the "Stopped" state and had not been started within the specific time interval. The duration of the interval is defined by "Unavailable Time" monitor property and could be overridden. By default this value is 900 secs (15 mins). If SQL DB Engine turns back to "Running" state faster than that time it means that it was just a restart.

If this monitor is too noisy in specific environment please increase "Unavailable Time". Otherwise if it is too latent, please reduce "Unavailable Time" setting.

In general windows service could be stopped by many reasons, including:
