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.

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

"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."

"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."

"I use it for monitoring infrastructure and it was very good for that issue."

"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 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."

"We monitor all, starting from UPS to international mail chains."

"Macros and the ability to connect it to Google Maps are valuable features."

"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."

More Icinga pros

"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."

"I like being able to see the flows coming in and out of the product. In terms of monitoring network flows, we use it to verify whether or not different servers/applications should be communicating with each other."

"We're a smaller company so it automates a lot of the tasks and lets us focus in on building out our own solution; it's quicker, there is less building of manual solutions, and less downtime, and it allows our developers to quickly develop, get provisioning done, de-provisioning, etc; the stuff that you would expect to be able to make it streamlined."

"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."

"Whenever we say "valuable" with respect to the network, it's more towards the security. The firewall rule issues it shows us and the recommendations that we get from vRNI are the most valuable features because they are actually making our network more secure."

"The solution is also extremely intuitive and user-friendly."

"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 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."

Cons

"The connection between Icinga and Icinga Web."

"The tool currently fails to provide notifications to users."

"The user interface should be improved."

"We have found some problems with Nagios, and support isn't very responsive."

"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."

"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."

"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."

"The solution lacks many features important to higher-level IT management and network support."

More Icinga cons

"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. That would be my only concern."

"It just needs to be more reliable and more accurate. At some point, there are some things where it does not match properly."

"Better integration into VRB."

"vRNI needs more remediation where it hooks into NSX."

"It needs improvement in terms of its efficiency."

"I would like to see them expand the capabilities to infrastructure types other than just VMware."

"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."

"There is room for improvement as not all cases are getting resolved, and we often do not get L3 support directly, having to go through L1 and L2, resulting in delays that usually are a headache for us."

Pricing and Cost Advice

"The solution is cheap."

"It's an open-source solution."

"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."

"The product is inexpensive compared to other DBM products."

"We're using the free version of Icinga."

"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."

"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."

"We have spent less time investigating network flows, so it is absolutely cost-effective."

"I rate vRealize Network Insight's pricing a seven point five out of ten."

"They should include the product in NSX because it's important to have it for deployment."

"It has brought more money into our company."

"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."

"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."
