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

"Overall, from one to ten, I rate Checkmk a nine."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"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."
"Checkmk helps me compare data and foresee issues."
"We can monitor multiple sites using the product."
"I really like the auto-discovery feature."
"The initial setup of Checkmk was easy...It is a very stable solution."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"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."
"I find that the interface of most VMware products is very similar, which I consider an advantage due to its ease of use compared to other tools like Splunk."
"Previously, we had no idea how the dataflow worked. We knew how all the applications and servers worked, but we never knew how the dataflow was happening."
"It's user-friendly. It's similar to the GUI that most VMware products are moving to, and the consistency across those makes it easy to switch from one product to another. Also, the search bar at the top is plain text and it helps you, it guides you along with your search query, so that helps. The first day you're in there you can start building actual queries."
"By doing dependency mapping, it makes migrations more efficient. There are less outages that require engineers to spend additional hours troubleshooting the migration failures."
"I find it user-friendly and intuitive. With the GUI interface that we do use on a regular basis, it's easy to navigate, it's easy to see, easy to query. We get reports. It's easy to use."
"We are better able to understand our needs for future growth and budgeting purposes."
"The most valuable features are the packet trace flow and that the view of the whole environment is deep."
 

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."
"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 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."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"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 initial setup is a bit complex."
"Checkmk does not allow running scripts at varying intervals."
"I would like to see application identification. That would be cool."
"Price. Honestly, the way it's licensed is challenging."
"The only real improvement they can make is to add more third-party vendors into the environment, mostly switch manufacturers, because it's really limited to Cisco equipment and there are a lot of companies out there other than Cisco."
"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."
"Support could be much better."
"The virtual appliance has rebooted, but overall, the stability is good."
"I'd like to see better support for being able to search the hardware NetFlow data."
 

Pricing and Cost Advice

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