What is Nagios?

“

- [Instructor] So what is Nagios? Nagios is an open source infrastructure monitoring and alerting system. It's been around a long time and it is an offshoot of an older program called NetSaint. Just to avoid confusion, it's helpful to know how to pronounce it. I've been using Nagios for a long time, and for most of that time, I pronounced it Nageeohs, emphasis on the nag, because it was the thing that would nag me when a server was down. But the name actually comes from a Greek word agios or hagios, which means holy, it's just a play on the name of NetSaint. I've been saying it wrong for quite a few years now, so it's quite likely during this course that I'll slip up and say Nadjios, or Nadios, or Nageeohs, or any of the other number of ways I might say it wrong. In this course, we're going to be covering the free open source part of Nagios, which is known as Nagios Core. There's also a commercial product called Nagios XI, which is based on Nagios Core. If you're looking for support and a smoother process, I'd recommend looking into it. The concepts we'll cover in this course will certainly apply to using the commercial product, but the free version is also very functional on its own. Nagios is a great piece of a systems monitoring and alerting solution, but it's important to realize its limits. Making Nagios your all-in-one solution is possible, but it's needlessly difficult, and I don't recommend it. Nagios plays well with a lot of different tools, including integrating with some great services like PagerDuty. We'll be looking at how to set up that integration as the final lesson for this course.
