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.
