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.

Automation and insightful diagnostics elevate operations while improvements are welcome
The new version 8.18 has brought significant improvements. The main purpose of using this tool is having a single console to manage all entities. The cloud integration capabilities, including private, public, and hybrid, are already well-implemented. The ability to manage multiple vCenters across different geographical locations is very effective. The new Skyline health feature and certificate and licensing management are particularly useful improvements. The dashboard's overview tab provides comprehensive information about current vCenter status, resizable amounts, reclamation opportunities, anomalies, diagnostics, licensing, and certificates. However, there is room for improvement in application analysis. The current functionality lacks detailed monitoring at the kernel level, focusing mainly on CPU, memory, and storage matrices. Enhanced application monitoring capabilities, including tracking downtime for specific types of applications such as transactional or e-commerce applications, would be beneficial.

Quotes from Members

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

Pros

"If you are a mid-sied company with an eye on expansion, this solution is very good."
"Nagios is the best software of its kind if you have time for configure any host and network, and you can do quite everything with a bit of scripting."
"The most valuable feature is the monitoring of processes."
"Overall, it's a powerful system."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"I really found Nagios a perfect fit for us and a good product to work with."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"The most valuable aspects of the solution are its ease of use and its ease of implementation."
"This solution allows me to have true visibility for any metrics when it comes to my cloud, and private."
"For us, the ease of deployment in combination with TMZ was the most important part because we don't have to manually deploy a complex monitoring solution. We can more or less do that with the click of a button, and we are not dependent on the developers to provide us with all the necessary features and functions to make that work. We can just deploy it on a workload cluster and monitor at least a good part of the workload. If we want to go into detail, we clearly need to make changes, but for a good part of application monitoring, it gives us good insights."
"We haven't had any issues with stability."
"VMware Aria Operations for Applications offers significant features such as real-time statistics, the ability to identify possible issues within the VM environment, and helpful heat maps."
"The solution provides single-console management for multiple VMware environments and cloud integrations, whether hybrid, private, or public cloud."
"I gladly recommend VMware Aria Operations for Applications because it is cost effective and has commendable AI response capabilities."
"Scalability for VMware Aria Operations for Applications is easy to implement and manage."
 

Cons

"I would like to see more customization in the network map because it is a bit tricky to use it."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The interface could be more user-friendly."
"It's in need of more standard plug-ins."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"The solution could be expensive, which might be a limiting factor."
"I would like to see integration with Kubernetes cluster and APIs so that you can manage the entire stack."
"The support from VMware is not very helpful. This is because you always receive many questions from the support service but few actual solutions."
"They could make it more easy to plug-in data so that a nontechnical person will be able to use it, like accountants or finance people. That way they don't have to ask us."
"An area for improvement would be more in-depth reporting, such as analyzing disk IO during business hours compared to after hours."
"In the new version, I would love to see more prediction capabilities. It would be great if one could see the alerts get a little more enriched with information and become more human-friendly instead of the technical stuff that they put in there. I think those would be really awesome outcomes to get."
"However, it is still not a very mature product."
"I find that there could be improvements in the support service response time, as the urgency varies unless specified as Priority 2 or 1 cases."
 

Pricing and Cost Advice

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Licensing costs are reasonable."
"As it is not an agentless tool, I think it is expensive."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is an expensive solution."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"The licensing costs are very high, particularly when you consider that we have to purchase a level 1 license for every integration, such as the load balancer, HAProxy, and the MSSP. And if you want to use vSAN, that's another license. Then, of course, Tanzu Observability has its own separate license."
"Different locations require different setups. In your terms, around 300 to around 400K USD."
"I don't have the details. In our case, there is a mixture in place. We have production usage, and we are also doing training for VMware. So, we also have a training instance. It is worth the money you would spend on it. That's because if you were to build all of this yourself by using some of the open source tools, then you would need a lot of time."
"I would rate the pricing as three out of five."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
