Harrison Bulley - PeerSpot reviewer
Senior Infrastructure Engineer at Net Consulting
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
Senior System Specialist at General Directorate of Residence and Foreigners Affairs (GDRFA)
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

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"Macros and the ability to connect it to Google Maps are valuable features."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"We have found the solution to be stable."
"Icinga does the job and is fairly stable."
"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."
"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 value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"By doing dependency mapping, it makes migrations more efficient. There are less outages that require engineers to spend additional hours troubleshooting the migration failures."
"A lot of time is saved when you use this type of software solution for the network. We have moved systems into the new data center and the servers and systems are much faster because of the very low latency between virtual machines."
"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."
"The ability to use the natural language query and see the visualization is quickly intuitive, and it works very well."
"The most valuable feature for us is that insight into what our network is really doing - it's a fairly complex network. Not having to go through thousands of lines of network configuration to find firewall ports that were open or closed, for various ports, was very valuable. It went out and found everything we need very quickly."
"We get proper reporting on different aspects such as utilization and health monitoring reports, including throughput details and network latency, and there are many things we can obtain from there."
"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."
 

Cons

"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"The user interface should be improved."
"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."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"We have found some problems with Nagios, and support isn't very responsive."
"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."
"The solution lacks many features important to higher-level IT management and network support."
"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."
"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."
"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."
"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."
"The compatibility with each and every component of the infrastructure is the main thing that I am looking for. I would like them to make sure that it's compatible with different kinds of storage systems, etc. I have seen the compatibility list. I feel it can be more compatible than it is right now."
"Since Broadcom acquired VMware, it has been experiencing challenges. Many sales processes are not well defined."
"The product is slightly complex use, while still being user-friendly. It could use more training modules, as it is not a straightforward product."
 

Pricing and Cost Advice

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