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.
Shaijith KB - PeerSpot reviewer
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."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"We can monitor multiple sites using the product."
"The alerting system in Checkmk really works properly."
"Overall, from one to ten, I rate Checkmk a nine."
"Checkmk helps me compare data and foresee issues."
"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."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"We haven't had any complaints about the stability of the solution or heard of any issues. None of our clients have mentioned running into bugs or glitches. There haven't been crashes."
"By doing dependency mapping, it makes migrations more efficient. There are less outages that require engineers to spend additional hours troubleshooting the migration failures."
"Login site gives you the opportunity to collect logs from all of your hypervisors and your virtual servers, then put them all in one location and make them searchable."
"It helps a lot because, until now, we didn't have the tools to figure out the micro level, VM-to-VM kind of traffic; that was not in the current environment. We could not figure out VM-to-VM communication from the other tools. This is the tool which gives us end-to-end transparency."
"It especially helps with deploying NSX, that you're not having to manually chase down and figure out what you need to do to microsegment VMs. This gives a nice option where you can say, "Hey, this VM, show me what flows are there." I can export it out and then import it as an NSX rule and job done."
"I would recommend the product."
"Network Insights has been pretty critical, helping me out."
"It allows you to see traffic that you couldn't otherwise see, which is traffic within your Layer 3-bounded network, meaning east-west traffic. It's hard to get that any other way."
 

Cons

"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."
"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."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"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 initial setup is a bit complex."
"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."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"Price. Honestly, the way it's licensed is challenging."
"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."
"Make the GUI easier to use."
"The virtual appliance has rebooted, but overall, the stability is good."
"The solution can be improved by making it more compatible with other brands, allowing for better integration."
"Support could be much better. They do not do a good job of finding issues."
"It needs improvement in terms of its efficiency."
"Support could be much better."
 

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."
"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 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."
"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 an expensive product because we have a lot of nodes."
"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."
"vRealize Network Insight is expensive."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
