Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect
It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. 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 alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

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 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."
"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."
"An affordable solution for small organizations to do basic network monitoring."
"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."
"We monitor all, starting from UPS to international mail chains."
"I would recommend Icinga; it's an open-source solution, it's quite easy and simple to use, and checks can be run with Python code and Shell Script code."
"People should know that it is simple and advanced."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"The most valuable feature is the profiling of the applications for micro-segmentation... It has made the migration to NSX much easier. Most of the sys admins within the smaller silos, they have no idea what ports are needed to run their stuff at all. I am pretty sure the micro-segmentation would never, ever have occurred without it."
"It has helped us tremendously to be able to easily deploy NSX in our environment with microsegmentation."
"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."
"If we can get it to provide those firewall rules it will literally save hundreds of man-hours, if not thousands of man-hours."
"I would recommend the product."
"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."
"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 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."
 

Cons

"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"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."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"The connection between Icinga and Icinga Web."
"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."
"I want to see more in terms of microsegmentation. As of now, I can see the rules, but they are not in a readable format that I can convert to microsegmentation and can fit into NSX Manager."
"I would like to see more interoperability on the firewall and low balancer sides."
"I would like to see application identification. That would be cool."
"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."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"It needs to be a little easier to use and to understand the information it's putting out."
"It needs improvement in terms of its efficiency."
"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."
 

Pricing and Cost Advice

"This is an open-source solution with paid support."
"It's an open-source solution."
"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."
"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."
"The solution is free to use."
"The product is inexpensive compared to other DBM products."
"vRealize Network Insight is expensive."
"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."
"It has brought more money into our company."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"It's an expensive product because we have a lot of nodes."
"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."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
