Senior System Administrator at Interactive Group
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

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"The most valuable feature is the performance parameters of the system."
"We can get real time statistics of our servers which improves our 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 feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The most valuable aspects of the solution are its ease of use and its ease of implementation."
"This solution allows me to have true visibility for any metrics when it comes to my cloud, and private."
"Using Wavefront, we have been able to reduce the complexity of our pipeline."
"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."
"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."
"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 provides single-console management for multiple VMware environments and cloud integrations, whether hybrid, private, or public cloud."
"I gladly recommend VMware Aria Operations for Applications because it is cost effective and has commendable AI response capabilities."
 

Cons

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"t was a little hard to get our setup represented in the configuration."
"Application level monitoring is limited."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"The initial setup should be easier and more seamless."
"The documentation and integration with Kubernetes could be improved."
"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."
"So far, the solution's learning curve has been pretty high."
"The support from VMware is not very helpful. This is because you always receive many questions from the support service but few actual solutions."
"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."
"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

"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is an open source solution, and there are no licensing fees."
"Most the plugin features are free."
"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."
"It's free."
"It's free."
"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."
