The Symantec Server Management Suite is an option for automating the management of servers and deployments.
Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.
The SMP suite is great at what it does, but it can be very complicated to learn how to get it to do what you want. It's a beast! However, when you learn how to the things you want to do, it comes as second nature and you complete them like they're supposed to be done that way. A lot of these things are done to be able to be completed a number of different ways. Take Patch Management, you can deploy patches automatically, via Jobs, or via the "Start Software Update Cycle Now" link in the SMP Agent!
Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.
The SMP solution is a beast. Each piece is complicated in itself let alone how everything ties together!
There is plenty of documentation online on how to perform a specific task, but you need to pay attention to what VERSION the article is written for. I've been halfway through implementing something only to hit a roadblock since I'm running a newer version and the option the article says to click on doesn't exist anymore...
We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.
The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.
I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.
Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].
With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
You can set up as many alerts as you want without incurring any fees.
Being able to report on the majority of things you want all from one interface, makes it really easy to get the results you want.
Because my employer didn't provide training, it took working with support, reading technical documentation, and just playing around on my own to learn how to do certain things.
I've had a lot of help from the SMP Support staff and they're great people and very helpful!
