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

"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"The alerting system in Checkmk really works properly."
"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."
"Checkmk helps me compare data and foresee issues."
"I really like the auto-discovery feature."
"Overall, from one to ten, I rate Checkmk a nine."
"We can monitor multiple sites using the product."
"It has really tightened down the security. That was something that we were lacking. It has also given us deep visibility into our network. We can really get down and see all of the traffic within the data center, between the VMs, between the applications, database servers, other application servers, web servers. We can identify everything that is communicating, and we can see it all on one product."
"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."
"If we deploy NSX it shows us how the workflow will flow in the organization, what the roadblocks are, and what we need to do to overcome those hurdles. When we run this product, it gives us reports which describe problems with physical switches. We work with the network team to get them all resolved."
"We are better able to understand our needs for future growth and budgeting purposes."
"It has really tightened down the security; that was something that we were lacking, and it has also given us deep visibility into our network so we can really get down and see all of the traffic within the data center, between the VMs, between the applications, database servers, other application servers, and web servers, identify everything that is communicating, and see it all on one product."
"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."
"We can see everything going on in NSX and get a good picture of our environment."
"This tool is critical because from a VMware perspective, it's really the only tool that does application rationalization."
 

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."
"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."
"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."
"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."
"Checkmk does not allow running scripts at varying intervals."
"In Checkmk, the documentation can probably be improved a bit more."
"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."
"It can be a bit painful to deploy."
"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."
"I would like to see application identification. That would be cool."
"If it were more application-aware, more descriptive; if it were able to determine the application that is actually doing the communication, that would be easier. More application information: which user or account it's accessing, is it accessing this application, doing these calls, if it is accessing a script, what script is it accessing. Things like that would provide deeper analytics so I can track what's going on. It would not just be, "These people shouldn't be talking," but who is actually doing these calls."
"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."
"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."
"While it's not exactly a feature, what normally happens when we are trying to look at the VM flow portion is - although Network Insight does have options to integrate a few physical switches into it - we can't really get an end-to-end flow of the network."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead. So if you choose an application, it will find the tiers within that application and say that it's communicating on, say, port 80 to a separate VLAN. There might be 200 machines in that other VLAN. You don't want to open port 80 at all of them. So we need a lot more granularity in those suggested firewall rules."
 

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."
"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."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
"They should include the product in NSX because it's important to have it for deployment."
"It's an expensive product because we have a lot of nodes."
"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."
"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."
