We use this solution for the monitoring of network devices in multiple areas. I use this solution on a daily basis, and the first thing that I do when I go into the workplace each morning is to check on all of the equipment.

It does exactly what we need: Alert us when something is wrong
We use Nagios because it does exactly what we need: Alert us when
something is wrong and (with PNP) show some trend to figure out when or
maybe how the problem started. The graphical output is for sure not
state of the art, but we are not artists but rather techs ;) As a hosting
business we have quite a homogenous infrastructure and use mostly snmp
for fetching data in our own scripts. Once the basic setup for Nagios
is done it is quite easy to automatically script new hosts when you add
new machines or delete the old ones. However your choice might be
different if you have to monitor IT of various customers with totally
different infrastructure.
And finally there are apps for android, iPhone, etc so with just one look at your phone you see if everything is well.

Network Engineer at a tech services company with 11-50 employees
Provides for better network visibility and identification of connection problems
Pros and Cons
- "The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
- "I would like to see more customization in the network map because it is a bit tricky to use it."
What is our primary use case?
How has it helped my organization?
This solution has improved our ability to determine the source of a connection failure in our network. Prior to using Nagios XI, we did not know whether the drop in service was a result of our system, or whether it was the fault of our service provider. Now, we are able to monitor the service provider's router and make that determination.
What is most valuable?
The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need. You can find and change your speed in the network topology, and if something goes down then it will be noticed immediately.
What needs improvement?
I would like to see more customization in the network map because it is a bit tricky to use it.
First, when you click on one of the devices on the map, it shows you information about the equipment. Sometimes, there is information that I do not want to show. I would instead like to choose what is shown.
Next, I would like to have the ability to show only a subset of equipment on the network map. When you view it, all of the equipment that you have is there, every time. Sometimes, I would like to choose just a group of devices to view.
For how long have I used the solution?
Four months.
What do I think about the stability of the solution?
This is a stable solution. On a scale of one to ten, I would rate the stability a nine.
What do I think about the scalability of the solution?
The scalability is perfect. I can add as much equipment as I like.
How are customer service and technical support?
I have not needed to contact technical support. Everything installed easily and it works fine.
Which solution did I use previously and why did I switch?
We did not use another solution prior to this one.
How was the initial setup?
The initial setup is very straightforward.
The deployment took approximately one hour. The difficult part is configuring the equipment, such as setting up the IP addresses. Because I have more than fifty devices, it took me some time. The task is simple, albeit repetitive.
What's my experience with pricing, setup cost, and licensing?
The licensing fees for this solution are approximately $3,000 USD per year.
Which other solutions did I evaluate?
When I was researching solutions I read about Nagios XI, and it was rated as one of the best solutions. I tried it and I liked it, which is why it was selected.
What other advice do I have?
I would rate this solution an eight out of ten.

R&D Support & Monitoring, IT Production at a tech vendor with 51-200 employees
Enables us to monitor servers but the visibility needs improvement
Pros and Cons
- "The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
- "There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
What is our primary use case?
We primarily use this solution to monitor servers and services.
What is most valuable?
The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful.
What needs improvement?
There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple. Going over the data and the information is complicated at the moment. The management of the commands is also a little complicated.

I have been using this solution for about half a year.
What do I think about the stability of the solution?
It's stable.
How are customer service and technical support?
I haven't had any experience with technical support.
How was the initial setup?
The initial setup was straightforward.
What other advice do I have?
In regards to the interface, obviously it can always get even better but at the moment it's functional. It's a good tool. It's very easy to use, very straightforward, and I would recommend it. I would rate this solution a seven out of 10. I like it but of course, it could be better. The product detail should look better, and again, being able to find information on the search is not good enough. I think to change that would improve it very much.

Nagios XI is open source.
It requires a yearly license.
What other advice do I have?
It is an alternative to more expensive solutions. That is why they use Nagios.

It's simple and has easily understandable monitoring concepts that have been largely adopted by the community.
Improvements to My Organization:
Starting from proprietary monitoring systems, it becomes possible to customize the monitoring system to our specific needs thanks to custom developments and community contributions.

Solutions Architect at Blue Telecom Consulting
Some kind of templating system for dashboards is needed. The Dashboards are easy to customize.
Valuable Features
It has a web front end and the Dashboards are really easy to customize.
Improvements to My Organization
We've been abel to integrate a human accesible interface for system monitoring our customers systems.
Room for Improvement
Backup mechanisms and some kind of templating system for dashboards are needed.
Use of Solution
I've been using it for two years.
Deployment Issues
We have had no issues with the deployment.
Stability Issues
We found certain stability issues that were solved by fine tuning some system parameters with support help.
Scalability Issues
It's been able to scale for our needs.
Customer Service and Technical Support
They have very accurate and fast support.
Initial Setup
The initial setup looked quite straightforward, however, later on we found some performance issues that required the fine tuning of system parameters. Those changes were not very well documented, but technical support helped us resolve the issues perfectly.
The implementation of officially supported features was quite easy. We were also required to extend the system with a couple of ad-hoc functionalities and development of these pieces of code was not easy due to the lack of in depth documentation.
Implementation Team
We performed the implementation in-house.
Other Solutions Considered
As they have their own official support, we decided to choose this product over the others we looked at.
Other Advice
Official support is a must have for working with this tool. If you want to cook it at home and face support on your own there are better alternatives with larger communities.

In-house. Its simple deployment but complexity comes once you have to import more plugins. Do check the required infrastructure support before deploying and check alerting mechanism.
Pricing, Setup Cost and Licensing
The community edition is free, and for an enterprise deployment its costing is good compared to other solutions.
Other Solutions Considered
I have tested Zenoss, ManageEngine solutions - Op Manager and Application Manager. We chose Nagios over Zenoss mainly because of its lightweight interface compared to Zenoss and the ManageEngine free edition has limited nodes.
Other Advice
First you need to do a complete analysis of the nodes and your requirements before implementing Nagios for monitoring.

Nagios is a very useful tool for system administrators, which provide good monitoring for network and servers. It's free and from my point of view it's fast and efficient. Nagios is stable and has many plugins available for monitoring. The software is robust, but, as a con, is an absolute pain to configure it. There is a very intuitive dashboard page that the administrator can leave open on an extra monitor to view at any given time and it will even rotate between different pre-selected views if the administrator likes that.
