I am trying to find out why my aws server keeps rebooting.

I am a developer and have very limited knowledge of administrating a server. After reading from questions on this topic in serverfault I was able to generate a log of when the server last rebooted and got these

reboot   system boot  3.13.0-115-gener Wed Jan  3 06:45 - 11:31  (04:45)
reboot   system boot  3.13.0-115-gener Mon Jan  1 23:57 - 11:31 (1+11:34)

wtmp begins Mon Jan  1 23:57:01 2018

But how do I find out why this happened.

From my server usage history I find it very unlikely that a system overload caused it. Here is the output of top currently

top - 11:40:19 up  4:54,  2 users,  load average: 0.00, 0.01, 0.05
Tasks: 122 total,   2 running, 120 sleeping,   0 stopped,   0 zombie
%Cpu(s):  2.0 us,  0.3 sy,  0.0 ni, 97.3 id,  0.3 wa,  0.0 hi,  0.0 si,  0.0 st
KiB Mem:   1016284 total,   791204 used,   225080 free,   116404 buffers
KiB Swap:        0 total,        0 used,        0 free.   263576 cached Mem

The server is a aws box running nodejs and mysql.

  • There have been a couple of emergency patches applied to AWS systems so it may be that. You may be better off asking AWS support although they're very slow in situations like this. – Simon Greenwood Jan 03 '18 at 12:01

Look in your system logs and see if there are any related/relevant messages. These are usually found in /var/log.
