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 good thing about Nagios Core is it covers everything."

"I like the way the solution sends alerts and how it keeps on escalating them."

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

"Provides timely notifications."

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"The application performance monitoring feature is valuable."

More Nagios Core pros

"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."

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

"The most valuable aspects of the solution are its ease of use and its ease of implementation."

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

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

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

"No issues with stability."

More VMware Aria Operations for Applications pros

Cons

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

"Would benefit from aggregations if a particular server goes down."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"The alerting mechanism in Nagios Core could be improved."

"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 and monitoring features could be improved."

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

More Nagios Core cons

"The implementation is a long process that should be improved."

"I would like to see integration with Kubernetes cluster and APIs so that you can manage the entire stack."

"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."

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

"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."

"It could use a URL document server. Everything in the market is moving towards automation and everybody's looking for the single click operations as well relational data locality."

"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

"I would rate the solution's pricing an eight out of ten."

"It's free."

"We are using the free version."

"The enterprise version has technical support. The version we are using is free."

"It's free."

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

"We are using the open-source, unpaid version."

"Nagios Core is free to use."

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 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."

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