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

"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"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."
"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."
"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."
"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."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"An issue that used to take days is now fixed within minutes to an hour."
"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."
"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 feature is the visualization, as it is really handy to be able to classify network objects with applications and see the interaction between them."
"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."
"I love what we can do with this and I love everything it gives to us."
"We haven't had any complaints about the stability of the solution or heard of any issues. None of our clients have mentioned running into bugs or glitches. There haven't been crashes."
"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 is user-friendly. It's pretty simple to deploy and to run. It gives you pretty easy-to-understand reports, very graphically intense, so you can visualize what's going on in your network."
"The ability to use the natural language query and see the visualization is quickly intuitive, and it works very well."
 

Cons

"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"I'd like them to make the product more user-friendly."
"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."
"It can be scalable. It just costs too much."
"There is a timeout feature that we have been asking for awhile."
"Sometimes, we can't access it."
"The NetFlow Collectors could handle more flows per minute."
"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."
"After you use it for a little while you become accustomed to it but the layout doesn't feel very intuitive."
"It needs to be a little easier to use and to understand the information it's putting out."
"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"Make the GUI easier to use."
"The only issue we have is that the solution does not always capture the host names."
"I would like to see more interoperability on the firewall and low balancer sides."
"Support could be much better. They do not do a good job of finding issues."
 

Pricing and Cost Advice

"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."
"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."
"I would like it to be more scalable with less spend."
"The price is a little high."
"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 rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
"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."
"It has brought more money into our company."
"They should include the product in NSX because it's important to have it for deployment."
"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."
