Earlier this year, I made an attempt to eval a network monitoring system (NMS); it lasted all of about 10 minutes once I realized that the software I was attempting to eval had to run on Windows.
So, with a week left of downtime before I return to the office, I decided to make an attempt at installing/evaling Nagios. This is the software I ran for several years prior to blasting my server to upgrade it to CentOS 7 a year or two ago.
In keeping with my normal eval process, I’m first attempting to spin up a VM and install it there. As of this writing, I’m currently in the middle of attempt number 10, and it just finished installing successfully for the first time! So off I go to play with it and put it through its paces.
