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."
"I think Goliath offers a very good tool to do simulated Citrix logons with actual user accounts and that the reports are useful to monitor and debug a session."
"Offers a diversity of features."
"In conclusion, I think Goliath Performance Monitor is a true winner."
"I would definitely give them high praise for what they do, and for being a special niche product."
"I like that the solution offers a diversity of things; it can give you resource monitoring, it can be integrated to detect an application crash, to capture syslog, things like that, and I like the diversity of the dashboard."
"My overall conclusion is that it is a valuable product for simulating Citrix logons because it does it with minimal effort and with a real user account."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Nagios is the best monitoring tool that I have ever worked on."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"The overall performance of the product is superb."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"The technical support is good."
"The most useful aspect of this solution is the ability to customize it for the client agent."
 

Cons

"However, its GUI can use a little help. The navigation is not the most straightforward like many other monitoring tools."
"With Goliath IT Monitors, the processing speed is very slow."
"Issues with generating reports; consistency is not there."
"I would love to be able to tell what ISP the user is coming from."
"The setup is a bit complex."
"Hardware requirements of the management server are kind of steep, 4cpu is quite a number."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"I would like to see support for notification via SMS."
"For some, it may be difficult to deploy."
"Nagios XI isn't really good for scaling, in my experience."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"There are stability issues if you have a large number of hosts and services."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The product does not have SAP monitoring."
 

Pricing and Cost Advice

"The price seems reasonable."
"Nagios XI is open source."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
