Monitors well with Citrix, stable, and the support is very responsive
It looks like it is easy to scale, but I don't know how far it can go out. We are only a 300, or 400 person company. We are not terribly large. It looks like it should be able to scale up until 10,000 at least. There are two users in the company who use this solution, I use it, and the helpdesk.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like that it not only has the ability to monitor but that it can do a lot of specific Citrix monitoring."
"Offers a diversity of features."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"I can monitor a phone on a desk to very big servers of any company."
"The solution is pretty stable."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"Nagios XI is stable."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The solution has a lot of plugins and scripts integrated with it."
"The dashboard allows you to see what's going on in the overall system."
 

Cons

"I would love to be able to tell what ISP the user is coming from."
"Issues with generating reports; consistency is not there."
"It can be quite difficult to know which drivers and agents to use when setting up."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"I would like to see support for notification via SMS."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The installation and monitoring need improvement."
"The tool's AI model needs to be fixed."
 

Pricing and Cost Advice

"The price seems reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Licensing costs are reasonable."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
