Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
ToniLindberg - PeerSpot reviewer
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 ability to set up templates and groups of checks, as well as customize the checks themselves."
"Nagios XI is a simple monitoring tool with performance management."
"I can monitor a software made in-house to software of bigger companies."
"It's great for monitoring IT services infrastructure."
"The solution is pretty stable."
"Nagios XI helped me to draw the network and check for system failures."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"People are very pleased with the implementation."
"This solution allows me to have true visibility for any metrics when it comes to my cloud, and private."
"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."
"I gladly recommend VMware Aria Operations for Applications because it is cost effective and has commendable AI response capabilities."
"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."
"The solution is great for virtualization and preparing the infrastructure in Tanzu to test products. It's very fast and has good visibility."
"It has a familiar interface, which makes it easy to get started."
"The solution provides single-console management for multiple VMware environments and cloud integrations, whether hybrid, private, or public cloud."
 

Cons

"The product's stability could be even better."
"Open-source software is usually not user-friendly."
"Technical support is an area that needs improvement. It is not available 24/7."
"The tool's AI model needs to be fixed."
"Nagios XI can improve its GUI for users with a new look."
"The user interface needs improvement."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The installation and monitoring need improvement."
"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 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."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
