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

"Offers a diversity of features."
"I would definitely give them high praise for what they do, and for being a special niche product."
"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."
"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."
"I like that it not only has the ability to monitor but that it can do a lot of specific Citrix monitoring."
"In conclusion, I think Goliath Performance Monitor is a true winner."
"Extensibility is good as this makes it easy to write checks on your own."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"I like the way the solution sends alerts and how it keeps on escalating them."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
 

Cons

"The setup is a bit complex."
"I would love to be able to tell what ISP the user is coming from."
"Hardware requirements of the management server are kind of steep, 4cpu is quite a number."
"With Goliath IT Monitors, the processing speed is very slow."
"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."
"The interface could be improved."
"The mapping is a little hard."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The core version is no match for the XI version."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"The mapping is a little hard."
"Application level monitoring is limited."
 

Pricing and Cost Advice

"The price seems reasonable."
"Nagios Core is a cheap solution."
"It's free."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"We are using the free version."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"The enterprise version has technical support. The version we are using is free."
"Nagios Core is an open source solution, and there are no licensing fees."
"We are using the open-source, unpaid version."

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
