Network Engineer at Inniti Network Solution
A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Senior System Specialist at General Directorate of Residence and Foreigners Affairs (GDRFA)
Comprehensive management and detailed reports benefit operations while improvements are needed in support and maintenance
We have Tanzu and OpenShift. We have OpenShift, Canonical, and the Tanzu one. The Tanzu platform from VMware is a Kubernetes platform. We haven't completely installed Tanzu yet; we installed the vROps part. vRealize Network Insight is beneficial because you can control the East-West traffic. vRealize has a component called NSX, which has East-West traffic controlling and micro-segmentation, that is one of the best options, and we have the layer extension, layer 2 extension possible through NSX. If you have anything accountable in any business, even in a candy business, having proper accountability on what you are selling and buying will save a lot. If you don't know what you're selling and buying, you will end up with a loss. My team does not use the flow analytics feature; we have a security and network monitoring team, which is a different SOC team. I am using it as an administrator internally. We perform different tasks including costing analysis, capacity management, and many other things. vRealize Network Insight has a concern about the maintenance part, as it requires a person to monitor it completely. It's not something you install and your report will be generated automatically. You have to work on this properly to get the insights. vRealize Network Automation, vRealize Operations, and vRealize Network Insight are completely related to the network. I cannot say much about these network aspects because I am on the operations side, but overall, the vRealize suite is good for reporting perspective or any ISO-related documentation; this is very helpful. The product is called vRealize Operations Manager, and now it is referred to as Aria or vAria. I am now a Senior System Specialist. We use different metrics because we have multiple departments, and we can monitor utilization and comparisons with the previous year. On a scale of one to ten, I rate this solution a seven.

Quotes from Members

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

Pros

"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"Sometimes it took a month to troubleshoot something that we can now do within days."
"One of the valuable features is the packet decoding."
"Also, the ability to troubleshoot all the way across the NSX part of it to the physical and actually watch the packets go through and then see where the bottleneck is or where the interruption is. We run queries on the network flows within the application to find where they are in it and it graphically tells us how the packets are actually going through the system."
"The tool's ease of configuration and use and the availability of information and artifacts through professional services and the web are key factors that customers find valuable."
"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."
"I would recommend the product."
"I find that the interface of most VMware products is very similar, which I consider an advantage due to its ease of use compared to other tools like Splunk."
"It helps a lot because, until now, we didn't have the tools to figure out the micro level, VM-to-VM kind of traffic; that was not in the current environment. We could not figure out VM-to-VM communication from the other tools. This is the tool which gives us end-to-end transparency."
"We're a smaller company so it automates a lot of the tasks and lets us focus in on building out our own solution; it's quicker, there is less building of manual solutions, and less downtime, and it allows our developers to quickly develop, get provisioning done, de-provisioning, etc; the stuff that you would expect to be able to make it streamlined."
"Without that, you're going to introduce additional latencies and problems into your environment that you don't want."
 

Cons

"Room for improvement exists in filtering in the packet decode."
"I would say that this is not a scalable solution."
"I would like to see improvements made to the user guide."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"There are some random glitches in the Web UI, but they are usually pretty cosmetic in nature. I don't really seem to use any browser other than Chrome with it. I also get some weird errors from time to time on the hardware NetFlow Collectors, where it doesn't sync data."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"There's enough information there, especially in the visualizations, but I would love to see this in a kiosk mode, where I could have a dashboard for interested stakeholders to see and appreciate what's going on. Then, moving on to a more practical level for our Help Desk, our operations team could benefit by seeing, in real-time, a visual view of the network."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead. So if you choose an application, it will find the tiers within that application and say that it's communicating on, say, port 80 to a separate VLAN. There might be 200 machines in that other VLAN. You don't want to open port 80 at all of them. So we need a lot more granularity in those suggested firewall rules."
"We're still going through the learning pains so we haven't quite got out of it most of what we're looking for, yet."
"It needs improvement in terms of its efficiency."
"If it had some kind of plugins with vSphere, more effective plugins with Horizon View or other VMWare products, if it had interconnectivity, I think it would be more effective than it is today."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
"It's an expensive product because we have a lot of nodes."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
"It has brought more money into our company."
"vRealize Network Insight is expensive."
"Cost always has room for improvement, you could always make it cheaper. But I think it's a good value for what you pay for it."
"The solution has reduced the time that we spend on other products. For example, with NSX, we were able to quickly find things that we would normally spend days trying to figure out."
