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 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 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."
"In conclusion, I think Goliath Performance Monitor is a true winner."
"Offers a diversity of features."
"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."
"I would definitely give them high praise for what they do, and for being a special niche product."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"The most valuable feature depends on the project; it's great if you need to check to ensure a service is running 24/7, I can use the full solution for free, and it's flexible."
"I like the way the solution sends alerts and how it keeps on escalating them."
"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."
"Dashboard provides monitor of total assets."
"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
 

Cons

"With Goliath IT Monitors, the processing speed is very slow."
"The setup is a bit complex."
"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."
"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."
"There is room for improvement in the graphics."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"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."
"The mapping is a little hard."
"The core version is no match for the XI version."
"The configuration and reporting modules need to be improved."
"The alerting mechanism in Nagios Core could be improved."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
 

Pricing and Cost Advice

"The price seems reasonable."
"Nagios Core is free to use."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Lessening the price point would be an improvement."
"The solution is expensive."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"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 product is cheaply priced."

What is your primary use case for Nagios Core?
I was a senior system administrator. I've been using Nagios Core for more than ten years now. It can be used to monitor hosts, such as machines, and monitor services of any kind. I'm using it to mo...
