NiFi queues drop dramatically when rebooted



Running NiFi 1.7.1 on Ubuntu 18.04.

I have a nifi instance on a physical laptop on one site sending SCADA and local resource monitoring data via S2S to another nifi instance in AWS.

Every day I have the laptop rebooting using cronjob.

I have noticed that the queue size drops about 10MB when the reboot occurs. I thought nifi keeps the contents of the queue even when rebooted.

Can I please ask for advice on how I can diagnose this, and to make sure there is no data being lost. I am trending the data on the AWS side and there doesn't seem to be any breaks...

Below are trends of the resource monitoring on the laptop. The reboot occurs at 0400.

Thank you
