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.

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

"I use it for monitoring infrastructure and it was very good for that issue."
"An affordable solution for small organizations to do basic network monitoring."
"Icinga does the job and is fairly stable."
"The apply rules feature saves a lot of time."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"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."
"Network Insights has been pretty critical, helping me out."
"To some degree, it has increased performance, helped to more easily manage networks, and provided visibility."
"If you are going to implement NSX, it's a great tool."
"It has really tightened down the security; that was something that we were lacking, and it has also given us deep visibility into our network so 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, and web servers, identify everything that is communicating, and see it all on one product."
"The most valuable feture is NetFlow to help us understand how VMs communicate with each other over ports that are known and ports that are also unknown to us. Our company is a security company, so it's very important for us to know exactly which VMs are doing what at all times."
"The most valuable feature is being able to easily see the path that the VM traffic is taking, what ports are in use."
"In large organizations where vSphere / SDDC / Private Cloud deployments have thousands of VMs and network segments that product definitely bring significant benefit in terms of monitoring, troubleshooting and granular details of network deployment and traffic of connected devices (physical or virtual) and last but not least holistic view of your network domain."
 

Cons

"One of the areas that are frustrating is remote monitoring for more than one machine."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"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."
"Sometimes, it is very hard to keep an overview of what's happening."
"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 tool currently fails to provide notifications to users."
"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."
"I want to be able to monitor a network flow that is approximately two weeks back, but I haven't found an easy way to do this."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"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."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead."
"It just needs to be more reliable and more accurate. At some point, there are some things where it does not match properly."
"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."
"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."
 

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."
"This is an open-source solution with paid support."
"The solution is cheap."
"The solution is free to use."
"It's an open-source solution."
"We're using the free version of Icinga."
"The product is inexpensive compared to other DBM products."
"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."
"Cost always has room for improvement, you could always make it cheaper. But I think it's a good value for what you pay for it."
"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."
"It has brought more money into our company."
"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."
