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. It has a very handy dashboard, providing live alerts and visibility for everything.

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

"Extensibility is good as this makes it easy to write checks on your own."

"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."

"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."

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

"The solution's most valuable feature is that it offers proper alerting capabilities."

"The reporting structure and the feature set are valuable to me."

"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."

"Nagios Core is very configurable. Whatever you want, you can do it."

More Nagios Core pros

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

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

"Scalability for VMware Aria Operations for Applications is easy to implement and manage."

"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."

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

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

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

More VMware Aria Operations for Applications pros

Cons

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

"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."

"The tool needs to improve the integrations."

"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."

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

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

"I like to have the option to configure Nagios using the web interface."

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

More Nagios Core cons

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

"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."

"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."

"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."

"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."

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

"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 initial setup should be easier and more seamless."

Pricing and Cost Advice

"Nagios Core is free to use."

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

"We are using the free version."

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

"It's free."

"Lessening the price point would be an improvement."

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

"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

"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."

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