EC2 instance was restarted automatically but there is no traces of the logs in the syslog or in any logs for the period instance is down. How can I find the reasons for the restart?

Hi EthanG,

It's linux? https://geekflare.com/check-linux-reboot-reason/ may help, there should be something in logs prior and after reboot?

What uptime is saying, does it's notice reboot and counting from 0 or uptime is still steady growing?

Thanks,

    I ran the last -x and I can see current (After reboot) and previous (before reboot) instance are in "running" status

    In link what I've provided you will see the reason why Linux was rebooted.

Checking if you are putting your instance under Auto Scaling Group. If the instance is failed during health check, it might be run new instance.
