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 stable."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"This is a very good solution and it is simple to use, for any company."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"I can monitor a software made in-house to software of bigger companies."
"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."
"People are very pleased with the implementation."
"It significantly improves application performance management by offering recommendations for resource allocation to avoid wastage or overcommitment."
"The most valuable aspects of the solution are its ease of use and its ease of implementation."
"The solution provides single-console management for multiple VMware environments and cloud integrations, whether hybrid, private, or public cloud."
"Scalability for VMware Aria Operations for Applications is easy to implement and manage."
"No 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."
 

Cons

"The Configuration Wizard needs improvement, because not all vendors are present."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"Technical support is an area that needs improvement. It is not available 24/7."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Nagios XI can improve its GUI for users with a new look."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"I would like to see support for notification via SMS."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"I would like to see integration with Kubernetes cluster and APIs so that you can manage the entire stack."
"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."
"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."
"The main problem I have is that the license cost is very high."
"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."
"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."
"The solution could be expensive, which might be a limiting factor."
"Its billing model is consumption-based. I understand the consumption-based model, but it is not necessarily easy to estimate and guess how many points or how much we are going to consume on a specific application up until we get to that point. So, for us, it would be helpful to have more insights or predictability into what we can expect from a cost perspective if we are starting to use specific features. This can potentially also drive our consumption a bit more."
 

Pricing and Cost Advice

"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."
"Nagios XI is open source."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"We are using the free version of this solution."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"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."
