EC2 crashes a few time a week last month

Question

In the last month my EC2 which hosts my blog went down 2 or 3 times every week. I have no idea why because it has running totally normally before that. I checked my blog frequently so I usually restarted it pretty fast but I am trying to solve the issue completely. Just wondering how I can see the reason for the crash of my EC2? Thanks

Answer

First of all, you can view the system log to see if there are any errors on the instance: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstances.html#troubleshooting-retrieve-system-logs

Secondly, you can view the detailed system log files to troubleshoot the issue

* For Linux systems, you can search files under `/var/log` (e.g. `/var/log/syslog`)

* For Windows systems, you can search the Windows Logs from Event Viewer (https://docs.microsoft.com/en-us/shows/inside/event-viewer)
