Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

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 solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"From a troubleshooting perspective, it allows us to quickly search all data TAP points in the network and helps our network engineers get to root cause quickly."
"Go with NETSCOUT."
"An issue that used to take days is now fixed within minutes to an hour."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"It is very rock solid, and we hardly have any hardware issues."
"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"Login site gives you the opportunity to collect logs from all of your hypervisors and your virtual servers, then put them all in one location and make them searchable."
"The gradual way the Network Insight shows you all the relevant information about your networks. It's pretty good. You can really dig deep deep inside and see where the problem is, where it comes from, what you have inside, how did you configure it. Also, it has alerts so you can have pretty much quite a big overview about your network. This is really something good."
"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"If you are going to implement NSX, it's a great tool."
"We can see everything going on in NSX and get a good picture of our environment."
"Technical support is great. They do excellent work."
"I find it user-friendly and intuitive. With the GUI interface that we do use on a regular basis, it's easy to navigate, it's easy to see, easy to query. We get reports. It's easy to use."
"It has given us much better insight into how we're deploying and how we perform after we deploy."
 

Cons

"The NetFlow Collectors could handle more flows per minute."
"We don't use the single pane of glass view, even though we own it."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"The monitoring and reporting tool needs improvement."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"There is a timeout feature that we have been asking for awhile."
"It can be scalable. It just costs too much."
"I'd like them to make the product more user-friendly."
"After you use it for a little while you become accustomed to it but the layout doesn't feel very intuitive. You have to dig around and find the exact place where you can find the information, where you can actually see your east-west traffic, etc. I would like them to bring that information more to the forefront, instead of having to find it."
"Maybe improve the fonts."
"I rate it a seven out of ten, only because it doesn't have all the vendors - at least the switch vendors - in there."
"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."
"I would like to see application identification. That would be cool."
"I would like to see more reporting features, more dashboards."
"Since Broadcom acquired VMware, it has been experiencing challenges. Many sales processes are not well defined."
"Price. Honestly, the way it's licensed is challenging."
 

Pricing and Cost Advice

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"I would like it to be more scalable with less spend."
"This product could be cheaper."
"The price is a little high."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"It has brought more money into our company."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
"It's a little expensive, but for what you're getting out of the product, you often see the trade-off. It depends on the type of licensing you have. It might be a little too pricey for some."
"They should include the product in NSX because it's important to have it for deployment."
"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."
"vRealize Network Insight is expensive."
"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."
