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.

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

"I really like the auto-discovery feature."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"Overall, from one to ten, I rate Checkmk a nine."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"We can monitor multiple sites using the product."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"The alerting system in Checkmk really works properly."
"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."
"The most valuable features are the packet trace flow and that the view of the whole environment is deep."
"If you are going to implement NSX, it's a great tool."
"In large organizations where vSphere / SDDC / Private Cloud deployments have thousands of VMs and network segments that product definitely bring significant benefit in terms of monitoring, troubleshooting and granular details of network deployment and traffic of connected devices (physical or virtual) and last but not least holistic view of your network domain."
"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."
"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"The gradual way the Network Insight shows you all the relevant information about your networks. It's pretty good. You can really dig deep deep inside and see where the problem is, where it comes from, what you have inside, how did you configure it. Also, it has alerts so you can have pretty much quite a big overview about your network. This is really something good."
"It has made the migration to NSX much easier."
 

Cons

"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."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"Checkmk does not allow running scripts at varying intervals."
"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."
"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."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"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."
"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."
"It needs improvement in terms of its efficiency."
"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."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead."
"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."
"It needs to be a little easier to use and to understand the information it's putting out."
"The only issue we have is that the solution does not always capture the host names."
 

Pricing and Cost Advice

"Checkmk is a fairly reasonably priced solution."
"The price of Checkmk is cheaper compared to other enterprise products."
"The product is affordable."
"vRealize Network Insight is expensive."
"It has brought more money into our company."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
"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."
"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."
"They should include the product in NSX because it's important to have it for deployment."
"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."
"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."
