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 product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
"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."
"It helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."
"It is very rock solid. We hardly have any hardware issues."
"The real-time troubleshooting and application segregation that you can do within it."
"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."
More NETSCOUT InfiniStreamNG pros
"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."
"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."
"It allows you to see traffic that you couldn't otherwise see, which is traffic within your Layer 3-bounded network, meaning east-west traffic. It's hard to get that any other way."
"The initial was straightforward. You can have it up and running in one hour."
"It's a very powerful, very manageable product."
"It allows us to go from virtual through NSX, up to the core, and see all of that in one pane of glass, it's pretty easy."
"If we deploy NSX it shows us how the workflow will flow in the organization, what the roadblocks are, and what we need to do to overcome those hurdles. When we run this product, it gives us reports which describe problems with physical switches. We work with the network team to get them all resolved."
"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. 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."

Cons

"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 stability depends on who is using the tool, because you only can get as much out of the tool as you put into it. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"I'd like them to make the product more user-friendly."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"I would like to see an improved level of stitching between IPs."
"It's not able to communicate with our probes."
"There is a timeout feature that we have been asking for awhile."
More NETSCOUT InfiniStreamNG cons
"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."
"It just needs to be more reliable and more accurate. At some point, there are some things where it does not match properly."
"I would like to see more reporting features, more dashboards."
"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."
"The only real improvement they can make is to add more third-party vendors into the environment, mostly switch manufacturers, because it's really limited to Cisco equipment and there are a lot of companies out there other than Cisco."
"The virtual appliance has rebooted."
"The product is slightly complex use, while still being user-friendly. It could use more training modules, as it is not a straightforward product."
"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."

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."
"This product could be cheaper."
"The price is a little high."
"I would like it to be more scalable with less spend."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"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."
"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."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"It has brought more money into our company."
"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."
"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."
"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."
"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."
