Reducing swap partition on lvm on ubuntu server

So the server I have hosted at Dacentec is starting to show its age and limitations. Luckily I can get my hands on some decent hardware thanks to ebay and other methods. So the past few days when time allows I have been working on building a replacement 1u server to what I currently have. In doing so I am taking the RAM from 16GB to 196GB. With that said the system is installed with a stock ubuntu 17.10 server using guided lvm partitioning. Which thinks like days of old where total ram equals the swap size needed.


What I do for my job is maintain a monitoring system for all the data centers for work and ensure it is getting good data. One thing I have found is many people tend to emulate work and personal lives together. So a bit over a month and a half ago for home use I went on a venture to figure out how can I monitor my home devices and network like I do for work to help identify problems before they begin. Now what I use for work is EM7 (by ScienceLogic) would be perfect to use. Only problem is it costs money to have a license for it. I did not want to spend money or hassle the work contacts (to much, I have already prodded them about the idea) to get a license for it. This left me looking to setup something free. So whats free out there? Nagios, Cacti, OpenNMS, LibreNMS, The Dude, and more. Those mentioned I have heard of or have tried to use, and that is not a complete list but those were the ones that stood out to me.
