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.

Consultant at HCLTech

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

"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."

"We use the product to monitor server applications."

"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."

"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."

"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."

"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."

"Provides timely notifications."

"Dashboard provides monitor of total assets."

More Nagios Core pros

"The features I find most valuable is the querying and alerting capabilities."

"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."

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

"Wavefront gives us the complexity we need, instead of spending time coming up with a nice dashboard from some other means, or just creating and coding our own app."

"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 is great for virtualization and preparing the infrastructure in Tanzu to test products. It's very fast and has good visibility."

"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 has a familiar interface, which makes it easy to get started."

More VMware Aria Operations for Applications pros

Cons

"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."

"The UI is a little outdated and graphics could be displayed in a better way."

"Nagios Core would benefit from aggregations if a particular server goes down."

"The dashboard and monitoring features could be improved."

"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."

"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."

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

More Nagios Core cons

"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."

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

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

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

"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."

Pricing and Cost Advice

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

"We are using the free version."

"Nagios Core is a cheap solution."

"The solution is expensive."

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

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

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

"It's free."

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."
