A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility

We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

The tool's configuration is easy and artifacts are easily accessible through professional services and the web

The product is highly regarded, and many customers have been using it along with other VMware products like vSphere and VMware vCloud Usage Insight. However, recently, there's been a trend among customers, especially those using VMware for a considerable period, to explore the potential of migrating to the public cloud. The common concern among these customers is how the VMware products will perform in the public cloud environment. Migrating instances from VMware to different platforms is not easy, especially when dealing with many instances across multiple customers. Customers are keen to maintain the functionality of their existing VMware products but prefer to run them on the public cloud instead of on-premise servers. Our clients for vRealize Network Insight are enterprise businesses. I rate it a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It's very easy to manage and monitor it."

"Being open source lets us customize it for our monitoring needs, saving us money."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

"The most valuable feature for us is that insight into what our network is really doing - it's a fairly complex network. Not having to go through thousands of lines of network configuration to find firewall ports that were open or closed, for various ports, was very valuable. It went out and found everything we need very quickly."

"The most valuable feature for me is the different views that you can get when selecting an application or a VLAN. It shows you the traffic flows. It gives you a visual representation of something that, in text, just may not make as much sense."

"The solution is extremely intuitive and user-friendly. When you log in to the application you are presented with a dashboard that is very reasonable for an initial user, and you can then customize it to your specific needs. But for all the data that we've found, we've only had to go through two or three drill-downs to get into that information."

"The most valuable feture is NetFlow to help us understand how VMs communicate with each other over ports that are known and ports that are also unknown to us. Our company is a security company, so it's very important for us to know exactly which VMs are doing what at all times."

"As a troubleshooting tool, it's a level-3 troubleshooting-skills tool and it's very easy to use and very easy to find the information that you need."

"The solution helps reduce time to value, increase performance, provide deep visibility, and easily manage networks."

"What's valuable to us is the ability to get a view into the virtual space, which is something we haven't had before. Before, it was done by collecting from network endpoints and extrapolating into the virtual environment. Now it's coming directly from the virtual environment."

"It gives the visibility that was either broken or there in pieces only. This solution provides a unified view of the whole system, back and forth. It has helped to reduce time to value, increase performance, more easily manage networks, and provide deep visibility."

Cons

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"Since Broadcom acquired VMware, it has been experiencing challenges. Many sales processes are not well defined."

"The product is slightly complex use, while still being user-friendly. It could use more training modules, as it is not a straightforward product."

"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."

"The only reason I would not give it a nine or a 10 is for cost reasons. It seems to be one of those things that really belongs as part of the product inherently and not as an add-on. That would be my only concern."

"While it's not exactly a feature, what normally happens when we are trying to look at the VM flow portion is - although Network Insight does have options to integrate a few physical switches into it - we can't really get an end-to-end flow of the network. We might be using a few switches that are not supported by Network Insight. That is where they can improve, in the support for more physical switches and network devices."

"After Broadcom acquired VMware, I would rate their support at five or less in many cases. It's difficult to find necessary documentation, open tickets, and get support."

"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."

"I want to see more in terms of microsegmentation. As of now, I can see the rules, but they are not in a readable format that I can convert to microsegmentation and can fit into NSX Manager."

More vRealize Network Insight cons

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."

"I rate vRealize Network Insight's pricing a seven point five out of ten."

"It's an expensive product because we have a lot of nodes."

"vRealize Network Insight is expensive."

"We have spent less time investigating network flows, so it is absolutely cost-effective."

"It has brought more money into our company."

"They should include the product in NSX because it's important to have it for deployment."

"The solution has helped us to reduce time, increase performance, reduce costs, and even easily manage networks. We are probably seeing 10 to 20 percent labor savings because we are able to be very specific and focused on what we want to do. It ends up saving the customer money and makes us be more efficient on our cost deliveries."

"It reduces costs. It takes something that may be challenging and makes it more usable and visual by being able to bring in tools, seeing what their impact is, such as microsegmentation and application rationalization, and seeing it quickly."
