Unexpected ubuntu server down

ru flag

I am using an Ubuntu Server 16.04LTS running ISP config that is hosted an VMware ESXi I experienced an unexpected shutdown issue, and I'm trying to identify the source. Upon checking the logs, I was unable to see the logs prior to the problem. The logs are appear's only after the server runtime

Action taken by my side:

I used to perform Journalctl command for the particular period of time but unable to get the logs 1.mysql database service restarted 2.ntp service restarted

Note: i can't get any of the service ( Mysql,apache,etc) before the shutdown

Kindly provide the solution for to fix the issue and the rootcause

are you saying ALL your log files only contain logs since the most recent boot? - why have you tagged `ntp` for this question? what does NTP have to do with anything?

According to my presumption, NTP services cause log entries to terminate, so I tagged NTP. there are no log entries during an unplanned server shutdown. hence it's challenging to identify a problem are you saying ALL your log files only contain logs since the most recent boot? -yes

Please read [this q&a](https://unix.stackexchange.com/questions/159221/how-do-i-display-log-messages-from-previous-boots-under-centos-7) to make sure you have logs enabled. If not, enable it. If you have it enabled, include them in your question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
