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 initial setup of Checkmk was easy...It is a very stable solution."
"Overall, from one to ten, I rate Checkmk a nine."
"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."
"I really like the auto-discovery feature."
"The alerting system in Checkmk really works properly."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"We can monitor multiple sites using the product."
"Checkmk helps me compare data and foresee issues."
"The best feature of this application is its ability to capture everything within the same application, as well as capture all the traffic."
"I would recommend the product."
"It provides deep visibility into what is happening with traffic and helps us manage our network."
"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."
"Technical support is great. They do excellent work."
"If you are going to implement NSX, it's a great tool."
"We get proper reporting on different aspects such as utilization and health monitoring reports, including throughput details and network latency, and there are many things we can obtain from there."
"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."
 

Cons

"In Checkmk, the documentation can probably be improved a bit more."
"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."
"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 allow running scripts at varying intervals."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"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 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."
"The pricing is steep."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"I would like to see more interoperability on the firewall and low balancer sides."
"In terms of room for improvement, customer education is number one."
"I want to be able to monitor a network flow that is approximately two weeks back, but I haven't found an easy way to do this."
"If it had some kind of plugins with vSphere, more effective plugins with Horizon View or other VMWare products, if it had interconnectivity, I think it would be more effective than it is today."
"However, stability is still in question because I don't think we have tested it to the core."
"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."
 

Pricing and Cost Advice

"The price of Checkmk is cheaper compared to other enterprise products."
"Checkmk is a fairly reasonably priced solution."
"The product is affordable."
"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."
"It has brought more money into our company."
"It's an expensive product because we have a lot of nodes."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
"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."
