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 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."
"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."
"I would definitely give them high praise for what they do, and for being a special niche product."
"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."
"Offers a diversity of features."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"We use the product to monitor server applications."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"Its an awesome product to use."
 

Cons

"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."
"I would love to be able to tell what ISP the user is coming from."
"With Goliath IT Monitors, the processing speed is very slow."
"I like to have the option to configure Nagios using the web interface."
"The configuration and reporting modules need to be improved."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"The core version is no match for the XI version."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"Lessening the price point would be an improvement."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"Nagios Core is not easy to use, so I don't recommend it for everyone."

"It's free."
"We are using the open-source, unpaid version."
"Most the plugin features are free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

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.

What is your primary use case for Nagios Core?
