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.

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

"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Dashboard provides monitor of total assets."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"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."
"Provides timely notifications."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
More Nagios Core pros
"Scalability for VMware Aria Operations for Applications is easy to implement and manage."
"It has a familiar interface, which makes it easy to get started."
"The stability of Aria Operations for Applications has improved significantly over the years."
"People are very pleased with the implementation."
"I gladly recommend VMware Aria Operations for Applications because it is cost effective and has commendable AI response capabilities."
"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."
"It significantly improves application performance management by offering recommendations for resource allocation to avoid wastage or overcommitment."
"The features I find most valuable is the querying and alerting capabilities."

Cons

"t was a little hard to get our setup represented in the configuration."
"The UI is a little outdated and graphics could be displayed in a better way."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The interface could be improved."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The user interface could be more interactive because it is pretty basic."
More Nagios Core cons
"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 solution could be expensive, which might be a limiting factor."
"The main problem I have is that the license cost is very high."
"An area for improvement would be more in-depth reporting, such as analyzing disk IO during business hours compared to after hours."
"The documentation and integration with Kubernetes could be improved."
"The initial setup should be easier and more seamless."
"I would like to see integration with Kubernetes cluster and APIs so that you can manage the entire stack."
"The implementation is a long process that should be improved."

Pricing and Cost Advice

"It's free."
"I would rate the solution's pricing an eight out of ten."
"The solution is expensive."
"We are using the free version."
"Nagios Core is a cheap solution."
"Nagios Core is free to use."
"The enterprise version has technical support. The version we are using is free."
"The product is cheaply priced."
More Nagios Core pricing and cost advice
"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."
