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

"The most valuable features are the reports and the way it generates the report in a graphical manner."

"The most valuable feature is the performance parameters of the system."

"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."

"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."

"I would rate the overall solution ten points out of ten."

"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"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."

More Nagios Core pros

"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 stability of Aria Operations for Applications has improved significantly over the years."

"It significantly improves application performance management by offering recommendations for resource allocation to avoid wastage or overcommitment."

"The solution provides single-console management for multiple VMware environments and cloud integrations, whether hybrid, private, or public cloud."

"Tanzu itself, integrated with multiple solutions, bestows support and security upon a container platform, especially when it comes to managing open-source container platforms such as Kubernetes."

"No issues with stability."

"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."

Cons

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"The scalability needs improvement, it's not scalable at this time."

"The initial setup process could be easier."

"The core version is no match for the XI version."

"The UI is a little outdated and graphics could be displayed in a better way."

"t was a little hard to get our setup represented in the configuration."

More Nagios Core cons

"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."

"An area for improvement would be more in-depth reporting, such as analyzing disk IO during business hours compared to after hours."

"The main problem I have is that the license cost is very high."

"The documentation and integration with Kubernetes could be improved."

"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."

"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."

Pricing and Cost Advice

"We are using the free version of Nagios Core."

"Lessening the price point would be an improvement."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"Nagios Core is a cheap solution."

"It's free."

"Nagios Core is an open source solution, and there are no licensing fees."

"We are using the free version."

"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."

More Nagios Core pricing and cost advice

"I would rate the pricing as three out of five."

"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 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."

"Different locations require different setups. In your terms, around 300 to around 400K USD."
