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 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."
"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"Macros and the ability to connect it to Google Maps are valuable features."
"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 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."
"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 value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"With this product, we can precisely identify communication patterns between virtual machines within our data center, whether it's east-east or east-west communication."
"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."
"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."
"The most valuable feature is being able to easily see the path that the VM traffic is taking, what ports are in use."
"It helps a lot because, until now, we didn't have the tools to figure out the micro level, VM-to-VM kind of traffic; that was not in the current environment. We could not figure out VM-to-VM communication from the other tools. This is the tool which gives us end-to-end transparency."
"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."
"The most valuable feature is the visualization. It's really handy to be able to classify network objects as with applications and see the interaction between them."
 

Cons

"The solution lacks many features important to higher-level IT management and network support."
"The installation and configuration are very complex."
"The tool currently fails to provide notifications to users."
"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."
"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."
"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."
"The user interface should be improved."
"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."
"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."
"The product is slightly complex use, while still being user-friendly. It could use more training modules, as it is not a straightforward product."
"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 solution can be improved by making it more compatible with other brands, allowing for better integration."
"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."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"vRNI needs more remediation where it hooks into NSX."
 

Pricing and Cost Advice

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