What is Nagios

Nagios is one of the best enterprise grade server monitoring solutions available. Unlike cPanel, it's available across a wide range of Linux distributions, including Debian and Ubuntu. Since Ubuntu 18.04 is an LTS release, upgrading your servers and running Nagios on them could be a great idea. Even though Nagios isn't up to date in the Ubuntu repositories, and setup isn't turn-key, it's still not too hard to get it running.

What is ELK

If you're in a situation where you manage large amonts of data logs, the ELK stack is exactly what you're looking for. The ELK stack combines Elasticsearch, Logstash, and Kibana into a simple, yet powerful, open source stack that lets you manage large amounts of logged data from a convenient graphical web interface. All three tools are developed by Elastic, so they work in tandem perfectly, and they're very easy to get set up on your Ubuntu system.
