I have an Ubuntu Server that is intermittently rebooting. I notice the reboot once every 3 weeks or so. I have a feeling that this is occurring more often and I want to get an accurate picture of the problem and how often it is occurring.
I was thinking about configuring an email that would be sent on server boot, but I wanted to ask the question here to see what is the best practice for monitoring servers. Noticed that you can configure server to send email by using Bootmail or by script using cron. I also noticed Nagios, but that seems a bit more complicated and detailed. What is the best practice for monitoring Ubuntu Servers? I am looking for something simple but yet flexible and powerful. The less shell scripting the better.
