Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Troubleshooting capabilities have improved application monitoring and support engagement
I can see what happens end to end, which is pretty beneficial. The solution has troubleshooting capabilities, providing a direct connection to knowledge base articles from VMware Broadcom. When I encounter an error, I can search directly within the system to see what solutions have been employed by others. It has a familiar interface, which makes it easy to get started.

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."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The most valuable feature is the performance parameters of the system."
"The good thing about Nagios Core is it covers everything."
"The application performance monitoring feature is valuable."
"Dashboard provides monitor of total assets."
"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."
More Nagios Core pros
"It significantly improves application performance management by offering recommendations for resource allocation to avoid wastage or overcommitment."
"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."
"No issues with stability."
"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."
"This solution allows me to have true visibility for any metrics when it comes to my cloud, and private."
"People are very pleased with the implementation."
"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 features I find most valuable is the querying and alerting capabilities."
More VMware Aria Operations for Applications pros
 

Cons

"The user interface could be more interactive because it is pretty basic."
"The scalability needs improvement, it's not scalable at this time."
"Nagios Core does not have a graphic display."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"There is room for improvement in the graphics."
"The dashboard and monitoring features could be improved."
"The alerting mechanism in Nagios Core could be improved."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
More Nagios Core cons
"The implementation is a long process that should be improved."
"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."
"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 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."
"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."
"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 initial setup should be easier and more seamless."
"The documentation and integration with Kubernetes could be improved."

Pricing and Cost Advice

"It's free."
"The solution is expensive."
"We are using the free version of Nagios Core."
"Nagios Core is free to use."
"I would rate the solution's pricing an eight out of ten."
"The product is cheaply priced."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The enterprise version has technical support. The version we are using is free."
More Nagios Core pricing and cost advice
"Different locations require different setups. In your terms, around 300 to around 400K USD."
"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."
"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."
