vRealize Network Insight Pros and Cons
vRealize Network Insight Pros
The ability to use the natural language query and see the visualization is quickly intuitive, and it works very well.View full review »
One of the most valuable features is the ability to look at the traffic flows, to look at NetFlow data.View full review »
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's user-friendly. It's similar to the GUI that most VMware products are moving to, and the consistency across those makes it easy to switch from one product to another. Also, the search bar at the top is plain text and it helps you, it guides you along with your search query, so that helps. The first day you're in there you can start building actual queries.View full review »
Whenever we say "valuable" with respect to the network, it's more towards the security. The firewall rule issues it shows us and the recommendations that we get from vRNI are the most valuable features because they are actually making our network more secure.
compare-to-competition; I would recommend the product. I don't think there is any other product like this on the market right now.View full review »
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.
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.
It's very user-friendly in the sense that the querying is just regular language like you and I speak or write. You don't need to know any SQL-query type of language to be able to get what you want out of it.
As a troubleshooting tool, it's a level-3 troubleshooting-skills tool and it's very easy to use and very easy to find the information that you need.View full review »
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 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.
It has definitely helped us to meet compliance rules by assuring that all traffic is going to where it's supposed to go. It can be used to report that you are in compliance, as well as helping you get into compliance.View full review »
It has really tightened down the security. That was something that we were lacking. It has also given us deep visibility into our network. We can really get down and see all of the traffic within the data center, between the VMs, between the applications, database servers, other application servers, web servers. We can identify everything that is communicating, and we can see it all on one product.
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.View full review »
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.View full review »
I like being able to see the flows coming in and out of the product. In terms of monitoring network flows, we use it to verify whether or not different servers/applications should be communicating with each other.View full review »
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.View full review »
vRealize Network Insight Cons
I would like to see more interoperability on the firewall and low balancer sides.View full review »
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.
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.View full review »
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.View full review »
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.View full review »
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.View full review »
It needs to be a little easier to use and to understand the information it's putting out. That would make it more helpful. If you're not a network person you need to understand things like network policies and concepts. If you gave it to a regular admin, it would be nice if it were easier for them to pick up what is going on, understand the flows and whether or not stuff should be talking to each other, as opposed to just port groups and IP addresses.
If it were more application-aware, more descriptive; if it were able to determine the application that is actually doing the communication, that would be easier. More application information: which user or account it's accessing, is it accessing this application, doing these calls, if it is accessing a script, what script is it accessing. Things like that would provide deeper analytics so I can track what's going on. It would not just be, "These people shouldn't be talking," but who is actually doing these calls.View full review »
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.View full review »
vRNI needs more remediation where it hooks into NSX.View full review »
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.View full review »
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 reason I would not give it a nine or a 10 is for cost reasons. It seems to be one of those things that really belongs as part of the product inherently and not as an add-on. That would be my only concern.View full review »
