After Finding and configuring our awesome new IT Ticketing system, I set my sights on upgrading our Server Monitor Solution. Right now we have a Legacy Server Monitor Program that was written by a company that doesn’t exist anymore… While it is still functional and fairly reliable, it is very rigid and it really is starting to show its age. I wanted to find a solution that was widely known and supported and if possible – Open Source. What I finally settled on was the Free Distribution of Nagios – FAN ( Fully Automated Nagios ). Let me Preface this Nagios Guide by stating that, It is indeed True what they say about Nagios… Super Powerful, But Pain in the ass to setup! Using NSClient++ with check_nrpe# NRPE is the most common way to connect to NSClient. NRPE works much like NRPE for unix (if you are familiar with it) and in short. Michael McConnell: Top doesn't display CPU usage of ipchains or ipvsadm. vmstat doesn't display CPU usage of ipchains or ipvsadm. Joe ipchains and ipvsadm are user. This is a list of notable port numbers used by protocols of the transport layer of the Internet protocol suite for the establishment of host-to-host connectivity. I tried for a good while to get Nagwin ( Nagios for Windows ) working in a functional way… And while I was able to setup Nagios core fairly easily, NONE of the front end interfaces were designed for Windows and I simply could not get them to work. Even if I were to figure out how to create the needed configuration Files needed to support Nagios Core, There was no way I was going to go to my Team and say they need to learn how to write config files if they ever want to monitor anything! So at this point I almost gave up on Nagios, Until I stumbled upon a Spiceworks Forum post where somebody recommended Nagios: FAN. ![]() ![]() I was still skeptical about using Linux, being almost entirely a Windows shop with very little Linux experience…. Nagios- FAN, my concerns were immediately put to rest. The setup process wasn’t nearly as intimidating as a Nagios Install from Scratch, and in fact after figuring out how to Install FAN as a Virtual Server on our Microsoft Hyper- V 2. Server – It was as easy as following the install directions. Now if you are looking for a point and click install that you can get setup inside of an hour…you may want to reconsider Nagios. Nagios is a Powerhouse, but with all the added Horsepower comes a fair deal of complexity ( especially if you don’t know Linux) That being said… It scales incredibly well, I think some companies have it monitoring over 1 MILLION DEVICES. If you still are on the fence about Nagios at this point, maybe it would help if you could see some of the companies that use and trust the product everyday.
