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.

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

"Icinga does the job and is fairly stable."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"We have found the solution to be stable."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"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."
"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."
"It gives the visibility that was either broken or there in pieces only. This solution provides a unified view of the whole system, back and forth. It has helped to reduce time to value, increase performance, more easily manage networks, and provide deep visibility."
"The best feature of this application is its ability to capture everything within the same application, as well as capture all the traffic."
"It provides deep visibility into what is happening with traffic and helps us manage our network."
"The tool's ease of configuration and use and the availability of information and artifacts through professional services and the web are key factors that customers find valuable."
"I find that the interface of most VMware products is very similar, which I consider an advantage due to its ease of use compared to other tools like Splunk."
"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."
 

Cons

"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."
"We have found some problems with Nagios, and support isn't very responsive."
"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."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"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."
"The installation and configuration are very complex."
"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."
"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."
"The UI, even though once you get to know it, it's easier, still it's hard to figure out by yourself. You have to go read, watch videos. It has a lot of data on it. So that is an issue."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"The IT infrastructure industry is expected to evolve towards a hybrid cloud model in the next five to ten years. In this model, most of the customer's resources reside on-premise within a private cloud setup, such as VMware. Another segment operates within public cloud environments like Azure and AWS, and a portion remains in traditional data centers. There should be seamless interoperability between public and private clouds. AWS and VMware need to work together to make it possible. Whether users interact with on-premise infrastructure or configure resources in the public cloud, the user experience must be seamless."
"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."
"Support could be much better."
"There is room for improvement when it comes to pricing because we pay here in Brazil, and all the costs are based on the dollar."
 

Pricing and Cost Advice

"The product is inexpensive compared to other DBM products."
"It's an open-source solution."
"The solution is cheap."
"The solution is free to use."
"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."
"We're using the free version of Icinga."
"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."
"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."
"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."
