Hi @pratiksha14 ,
Yes, that is right. OneAgent would auto-start when the server is rebooted.
For a scenario where the server is restarted, Dynatrace would notify that the connection with the server would be lost and the monitoring is not available. Once the server is restarted, all the services within the server would kick start along with Dynatrace. This will allow the Dynatrace problem to auto close as the monitoring of the server (Host) is back online.
You can always check the status of the OneAgent services with the following command:
Auto start of the services is a proactive method to make sure that the monitoring is always available.
