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.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

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

Pros

"I would definitely give them high praise for what they do, and for being a special niche product."
"In conclusion, I think Goliath Performance Monitor is a true winner."
"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 it not only has the ability to monitor but that it can do a lot of specific Citrix monitoring."
"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."
"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."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"We can get real time statistics of our servers which improves our monitoring."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"Provides timely notifications."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
 

Cons

"With Goliath IT Monitors, the processing speed is very slow."
"I would love to be able to tell what ISP the user is coming from."
"However, its GUI can use a little help. The navigation is not the most straightforward like many other monitoring tools."
"Issues with generating reports; consistency is not there."
"Hardware requirements of the management server are kind of steep, 4cpu is quite a number."
"The setup is a bit complex."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"The initial setup process could be easier."
"The alerting mechanism in Nagios Core could be improved."
"Generally, it does what I need it to do, but better error reporting would be great."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"Nagios Core would benefit from aggregations if a particular server goes down."

"We are using the free version of Nagios Core."
"The product is cheaply priced."
"It's free."
