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.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

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."
"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."
"We can monitor multiple sites using the product."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"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 is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"They have very accurate and fast support."
"The ROI is very good."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios is great for verify quality and quantity in a datacenter."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
 

Cons

"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"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."
"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."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"Checkmk does not allow running scripts at varying intervals."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down."
"The reporting structure could be more streamlined."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"The GUI could be improved."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
 

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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"The pricing is high with separate licensing for the product and support."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
