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 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."
"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."
"I would definitely give them high praise for what they do, and for being a special niche product."
"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."
"In conclusion, I think Goliath Performance Monitor is a true winner."
"I like that it not only has the ability to monitor but that it can do a lot of specific Citrix monitoring."
"I can monitor a software made in-house to software of bigger companies."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"I really found Nagios a perfect fit for us and a good product to work with."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"It has a lot of flexibility for customization and a wide range of metrics."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
 

Cons

"Hardware requirements of the management server are kind of steep, 4cpu is quite a number."
"I would love to be able to tell what ISP the user is coming from."
"Issues with generating reports; consistency is not there."
"However, its GUI can use a little help. The navigation is not the most straightforward like many other monitoring tools."
"The setup is a bit complex."
"With Goliath IT Monitors, the processing speed is very slow."
"It's in need of more standard plug-ins."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"Nagios XI isn't really good for scaling, in my experience."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The product does not have SAP monitoring."
"I would like to see support for notification via SMS."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"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."
 

Pricing and Cost Advice

"The price seems reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Licensing costs are reasonable."
"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."
