I need to monitor when a Windows service stops. I have tried enabling Windows add-ons and configured the alert in the windows.service\_state chart, but when, for example, the sqlagent service stops, no alert is triggered.  
Can you help me?

When your Netdata service stops running, Windows may cease exposing data to the collector.

Could you please confirm if the service still appears visible in your dashboard charts?

If it is not exposed, you could try something like `warn: $this != nan`.

Best regards,
