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

"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"It has a lot of flexibility for customization and a wide range of metrics."
"It's very easy to install it and manage it with Nagios XI's interface."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"I gladly recommend VMware Aria Operations for Applications because it is cost effective and has commendable AI response capabilities."
"We haven't had any issues with stability."
"This solution will give you a single pane of glass for everything, and centralized monitoring."
"Wavefront gives us the complexity we need, instead of spending time coming up with a nice dashboard from some other means, or just creating and coding our own app."
"It significantly improves application performance management by offering recommendations for resource allocation to avoid wastage or overcommitment."
"VMware comes with a support team, and if you have trouble, you can easily create a ticket, and VMware will help you. Therefore, the best aspect is the support."
"I find VMware Aria Operations for Applications to be very stable, and I would rate it a ten out of ten."
"The stability of Aria Operations for Applications has improved significantly over the years."
 

Cons

"The reporting structure could be more streamlined."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"We're still experiencing stability issues with regards to collecting performance graphs."
"The interface could be more user-friendly."
"Implementation on Windows was painful."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"The user interface needs improvement."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"However, it is still not a very mature product."
"The initial setup should be easier and more seamless."
"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."
"VMware technical support has declined since the Broadcom acquisition. Previously, they were more focused on issue resolution, but now they prioritize licensing verification before providing support."
"So far, the solution's learning curve has been pretty high."
"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."
"The return on investment is best suited for organizations that do not have the resources for a dedicated VM environment team. However, the cost of the product doesn't show significant benefits."
"They just need more capability. A few areas still need more enhancements in the technology capability space."
 

Pricing and Cost Advice

"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"Nagios XI is open source."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"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."
"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."
"I would rate the pricing as three out of five."
"Different locations require different setups. In your terms, around 300 to around 400K USD."
