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

"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."

"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 cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."

"Go with NETSCOUT."

"The real-time troubleshooting and application segregation that you can do within it."

"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."

"This solution has saved us hours (three to four) per problem when troubleshooting."

"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."

More NETSCOUT InfiniStreamNG pros

"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."

"It has given us much better insight into how we're deploying and how we perform after we deploy."

"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 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."

"It has enabled us to set up and do application discovery, as far as network traffic is concerned, and set up the appropriate rules that we need to make sure we're compliant with our security frameworks."

"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."

"The automation collects all the relationships between servers, allowing us to visualize these relationships and organize the migration into waves."

More vRealize Network Insight pros

Cons

"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."

"There is a timeout feature that we have been asking for awhile."

"I'd like them to make the product more user-friendly."

"It can be scalable. It just costs too much."

"Sometimes, we can't access it."

"The solution is not great, but it is not bad."

"I would like to see an improved level of stitching between IPs."

"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."

More NETSCOUT InfiniStreamNG cons

"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."

"Support could be much better."

"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."

"I'd like to see better support for being able to search the hardware NetFlow data. It ingests fairly well, but you can't tell, in a lot of cases, what source the data came from. I'd like to see more support for picking specific sources. That way you could really make a compelling use case. There are also some difficulties where it can't exactly trace the path between source and destination but if you hit the reverse flow on the same search it shows the entire path."

"I would like to see application identification. That would be cool."

"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."

"The UI, even though once you get to know it, it's easier, still it's hard to figure out by yourself. You have to go read, watch videos. It has a lot of data on it. So that is an issue."

"Technical support has been responsive. The response has always been immediate. Whether or not they've fixed it immediately is a different story."

Pricing and Cost Advice

"I would like it to be more scalable with less spend."

"This product could be cheaper."

"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."

"The price is a little high."

"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 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."

"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."

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

"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."

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

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

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