IT Administrator at a construction company with 201-500 employees
Utilizing data monitoring capabilities and scripting potential to optimize system management
I frequently program functions with PowerShell, and although Bash could be used, my specialization is in PowerShell. Two of us focus on programming in PowerShell for infrastructure optimization. I set up a dedicated server to run scripts every hour, generating files for Checkmk output. However, Checkmk does not allow running scripts at varying intervals. I am working on this in the raw version of Checkmk.

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

"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"Overall, from one to ten, I rate Checkmk a nine."
"Checkmk helps me compare data and foresee issues."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"The initial setup of Checkmk was easy...It is a very stable solution."
"The alerting system in Checkmk really works properly."
"I really like the auto-discovery feature."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"We can see everything going on in NSX and get a good picture of our environment."
"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."
"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."
"The most valuable features are the monitoring and tracking. It's also intuitive and user-friendly. The screen looks exactly the same as the other appliances for VMware, so it's easy to navigate."
"The solution helps reduce time to value, increase performance, provide deep visibility, and easily manage networks."
"If we can get it to provide those firewall rules it will literally save hundreds of man-hours, if not thousands of man-hours."
"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 solution has helped improve our organization by directing the network traffic using SDN."
 

Cons

"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."
"The initial setup is a bit complex."
"Checkmk does not allow running scripts at varying intervals."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."
"In Checkmk, the documentation can probably be improved a bit more."
"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."
"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."
"Support could be much better. They do not do a good job of finding issues."
"There are some random glitches in the Web UI, but they are usually pretty cosmetic in nature. I don't really seem to use any browser other than Chrome with it. I also get some weird errors from time to time on the hardware NetFlow Collectors, where it doesn't sync data."
"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."
"The product is slightly complex to use, while still being user-friendly. It could use more training modules, as it is not a straightforward product."
"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."
"The only issue we have is that the solution does not always capture the host names."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead."
"It needs improvement in terms of its efficiency."
 

Pricing and Cost Advice

"The product is affordable."
"Checkmk is a fairly reasonably priced solution."
"The price of Checkmk is cheaper compared to other enterprise products."
"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."
"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."
"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."
"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."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
