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 alerting system in Checkmk really works properly."
"We can monitor multiple sites using the product."
"Checkmk helps me compare data and foresee issues."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"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 initial setup of Checkmk was easy...It is a very stable solution."
"I really like the auto-discovery feature."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"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."
"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"By doing dependency mapping, it makes migrations more efficient. There are less outages that require engineers to spend additional hours troubleshooting the migration failures."
"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 a pretty good system if you're doing troubleshooting and microsegmentation."
"The network assurance is great, it's useful for analyzing networks, offers good data integration with other products, and is a very powerful, very manageable product."
"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."
"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."
 

Cons

"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."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"The initial setup is a bit complex."
"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 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."
"The pricing is steep."
"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."
"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."
"I rate it a seven out of ten, only because it doesn't have all the vendors - at least the switch vendors - in there."
"It needs to be a little easier to use and to understand the information it's putting out. That would make it more helpful. If you're not a network person you need to understand things like network policies and concepts. If you gave it to a regular admin, it would be nice if it were easier for them to pick up what is going on, understand the flows and whether or not stuff should be talking to each other, as opposed to just port groups and IP addresses."
"Support could be much better. They do not do a good job of finding issues."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"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."
 

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."
"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."
"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."
"vRealize Network Insight is expensive."
"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."
"It has brought more money into our company."
"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."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
