Harrison Bulley - PeerSpot reviewer
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.
Shaijith KB - PeerSpot reviewer
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 value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated."
"An affordable solution for small organizations to do basic network monitoring."
"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."
"The apply rules feature saves a lot of time."
"Macros and the ability to connect it to Google Maps are valuable features."
"It allowed us to set up NSX and to do microsegmentation, without all of the pain points of having to determine each port and each IP address that needed to have access, and which ones needed to be blocked."
"The ability to use the natural language query and see the visualization is quickly intuitive, and it works very well."
"What's valuable to us is the ability to get a view into the virtual space, which is something we haven't had before. Before, it was done by collecting from network endpoints and extrapolating into the virtual environment. Now it's coming directly from the virtual environment."
"It especially helps with deploying NSX, that you're not having to manually chase down and figure out what you need to do to microsegment VMs. This gives a nice option where you can say, "Hey, this VM, show me what flows are there." I can export it out and then import it as an NSX rule and job done."
"The graphical interface of this environment is so good with all the views, the graphics, and everything in them. It's really easy for me. It doesn't need an engineer to work on it. It's easy enough that anyone can get into the environment and look for issues or look at how communication is going on across the VMs. It's pretty much straightforward."
"It's a very powerful, very manageable product."
"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"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."
 

Cons

"One of the areas that are frustrating is remote monitoring for more than one machine."
"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."
"We have found some problems with Nagios, and support isn't very responsive."
"The solution lacks many features important to higher-level IT management and network support."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"The user interface should be improved."
"The installation and configuration are very complex."
"Support could be much better."
"The only issue we have is that the solution does not always capture the host names."
"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."
"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."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"This is an open-source solution with paid support."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"It's an open-source solution."
"The product is inexpensive compared to other DBM products."
"The solution is cheap."
"We're using the free version of Icinga."
"The solution is free to use."
"It's an expensive product because we have a lot of nodes."
"vRealize Network Insight is expensive."
"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."
"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."
"They should include the product in NSX because it's important to have it for deployment."
"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."
