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

"We use the product to monitor server applications."

"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."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"Provides timely notifications."

"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."

"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."

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

More Nagios Core pros

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

"This solution allows me to have true visibility for any metrics when it comes to my cloud, and private."

"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."

"I find VMware Aria Operations for Applications to be very stable, and I would rate it a ten out of ten."

"I gladly recommend VMware Aria Operations for Applications because it is cost effective and has commendable AI response capabilities."

"No issues with stability."

"People are very pleased with the implementation."

"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."

More VMware Aria Operations for Applications pros

Cons

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

"It is a bit slow due to latency."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"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."

"The dashboard should be improved."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"I would like to see more training videos."

"The tool needs to improve the integrations."

More Nagios Core cons

"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."

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

"The solution could be expensive, which might be a limiting factor."

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

"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."

"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."

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

More VMware Aria Operations for Applications cons

Pricing and Cost Advice

"Most the plugin features are free."

"It's free."

"The solution is expensive."

"Nagios Core is free to use."

"Nagios Core is a cheap solution."

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

"The product is cheaply priced."

"It's free."

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."

"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."
